PIR & Microwave Sensor Switches, Modules and Remotes from TUODI, China
TUODI designs and builds its own sensing electronics, the line it started with in 2005. Two engineering details recur across the range: Excelitas PIR elements behind precision Fresnel lenses with 4 mm² solid-copper terminals on the wall plates, and TUODI's own temperature-compensation chip in the ceiling and swivel switches, built for the common complaint that PIR range drops in hot weather.

- Radar (microwave) sensor switches that sense through some plastics and thin panels
- OEM sensor modules and retrofit interfaces for lighting brands
Certification: the sensor switch range is not certified as standard. Certification can sometimes be arranged per project; a lab quote is not a certificate.

Ceiling Occupancy Switches
Recessed barrel switches for corridors and stairwells: TDL-9956J (10 A relay, spring-clip mounting) and TDL-9959J, plus a Tuya Wi-Fi variant (TDL-9953PIR-BL) for smart-building integrators.
Wall-Plate PIR Switches
Flush 86-type plates with Excelitas PIR + Fresnel optics and 4 mm² solid-copper terminals. The current catalogue model is the TDL-2200J: 100–240 V AC, 10 A, with a three-step delay (30 s / 3.5 min / 6 min) and a three-step daylight setting, 5–8 m detection, 86 × 86 × 43 mm.
The 86-Type Wall-Plate PIR Switch (TDL-2280J) remains available to order, subject to component stock for the requested quantity.
Microwave Radar Sensor Switches
Doppler-radar switches sense through some plastics and thin panels. The Plug-Through Microwave Switch (TDL-2076WB) runs at 85–277 V AC, covers up to 8 m through 360°, and offers six sensitivity steps plus 3 / 15 / 30 / 60 s delay settings; loads are incandescent 1200 W, CFL or fluorescent 600 W, and LED 150 W maximum. The Microwave Ceiling Switch (TDL-1915) suits hotel corridors and stairwells (AC 85–250 V, 2–16 m adjustable, 8 s–12 min delay, 2–2000 lux, 70 mW standby, all three set by rotary trimmers).

Human Presence Switches
Lights that stay on for someone sitting still, the one thing PIR cannot do, for offices, meeting rooms and bathrooms. TUODI's 2026 catalogue lists a 24 GHz presence range: the TDL-9952 ceiling family, selected TDL-9953 variants, TDL-7159 in-luminaire modules and the TDL-2076-EX corded puck, with detection distances, delay ranges and light-control steps. The TDL-9953B-J uses 5.8 GHz instead; compare the TDL-9953 variants below. None has a radio certificate yet, and a transmitting sensor counts as radio equipment in most markets; tell us the room type, hold time and destination and you get the specification and the certification answer together.

Hand-Wave & Cord-Set Switches
Inline switches that install by plugging cords together: the Inline Hand-Wave Toggle (TDL-7158WB-T) for T5/T8 battens, Plug-Lead PIR Switch (TDL-2086), and photocell dusk-to-dawn switches.
Hand-wave switches
Timer & Countdown Switches
86-type countdown plates for charging bays, laundry rooms and stairwells: Three-Step Countdown Timer (TDL-2116) and 16-Step DIP-Selectable Timer (TDL-2115).
Timer switches
OEM Modules & Retrofit Interfaces
Board-level PIR modules with screw-in probes, a 12 V-to-mains relay interface, RF remotes and wireless modules (the technology behind the TDL-6110XRF-DJ spliceable system), and low-voltage DC cabinet accessories.
OEM modules
Touchless Faucet Adapters — SR-M01 / SR-T01
Touchless faucet adapters shipping with standard M22/M24 thread adapters: SR-M01 senses hands near the spout (short-flow), SR-T01 toggles by hand-wave (long-flow); both auto-stop after 180 s if you forget. 0.25-second sensing, IPX6 marking, built-in aerator — and a 4000 mAh battery rated 5–10 years with no recharging, backed by a 3-year factory warranty (2026 spec).
US$16.28 a unit at 100–500 units (SR-M01 or SR-T01)
Key-Card Power Switches
Hotel energy-saving systems from TUODI's electrical line can use a wireless card panel and relay receiver, with no control wiring between them. No model number or current product offer is available yet; send the room count and loads for a project review.
TDL-9953 ceiling switches
For ceiling-mounted lighting control in living rooms, meeting rooms, warehouses, hotels, offices and corridors. The model suffix sets the power supply, output and sensing technology.
| Model | Input and output | Sensing / distance | Delay |
|---|---|---|---|
| TDL-9953BJ-DC | 12 V DC; dry-contact output | 24 GHz presence sensing; 3–5 m | 30 s |
| TDL-9953B-J | 100–240 V AC; 800 W factory rating | 5.8 GHz microwave; 3–5 m | 30 s |
| TDL-9953A-J | 100–240 V AC; 800 W factory rating | 24 GHz presence sensing; adjustable, up to 8.4 m | 15 s–18 h, adjustable |
| TDL-9953BJ-BM | 100–240 V AC; 800 W factory rating | 24 GHz presence sensing; 2.4–6.6 m, adjustable | 5–600 s, adjustable |
The 800 W rating does not name a load type, so tell us the LED driver or other load, wiring, installation height and detection field you plan to use.
TDL-2025 low-voltage LED-strip controllers
For LED-strip control in homes, hotels, offices and shops. Choose a PIR motion-sensor version for movement-triggered lighting, or the CDS version for dusk-to-dawn control. These controllers use an external DC supply; select the matching voltage and load.
| Model | Supply / load rating | Control | Delay / operation |
|---|---|---|---|
| TDL-2025 | 6–24 V DC / 5 A | PIR with daylight control | 18–360 s, adjustable |
| TDL-2025-USB | 5 V DC / 2 A | PIR with daylight control | 18–360 s, adjustable |
| TDL-2025Type-C | 5 V DC / 2 A | PIR with daylight control | 18–360 s, adjustable |
| TDL-2025-CDS | 6–24 V DC / 5 A | Photocell; no PIR motion sensing | Off in daylight, on at night |
Fitting, plugs and indoor use
The 86-type flush plates fit an 86 × 86 mm back box, standard in China, Southeast Asia and the Middle East (not EU 60 mm round or North American boxes). Cord-set products ship on a Chinese GB 2-pin plug that is changed to your market's plug at order time. Tell us the destination and we spec accordingly.
Specify the switches as indoor products. The TDL-2086 and TDL-2076WB carry an IP54 marking and the SR-M01 / SR-T01 faucet adapters an IPX6 marking; these are the factory's own markings with no third-party ingress test, and the factory does not recommend the switches outdoors.
Certification can be arranged per project, depending on model, scheme, market and voltage class. Unlike the lighting and white-noise ranges, the switches carry no standing CE, RoHS or FCC documents; tell us the model and destination before you write it into a tender.
Datasheets by model. Tell us your application and ask for the voltage range, load rating, detection parameters and wiring diagram of the model you choose. Request datasheets on WhatsApp →
Run-out stock

Swivel-Head PIR Switches
Run-out — not for new designs. The Swivel-Head PIR Switch (TDL-2100BJ; 220 V AC, 800 W, 7–10 m detection, 5–500 lux threshold, 30–350 s hold; time, lux and direction adjustable on the head) is discontinued and remaining stock is being cleared. We quote it while stock lasts. Do not write it into a tender or long-run BOM; tell us the application and we will propose the current equivalent.
Notes
TDL-2200J: design to 100–240 V; a wider 85–277 V figure circulates but belongs to a different model until the factory confirms otherwise.
TDL-2280J: confirm quantity, current electrical specification and lead time before designing it into a repeat programme. A 2021 commissioned test report exists for this model, but a copy is not currently available. Request it only after its tested build is matched to the quoted build. It is a test report, not a certificate.
Microwave switches: confirm the selected model, sensitivity, mounting position and behaviour through the actual panel or enclosure on the sample. The TDL-1915 has no radio certificate today; CE/RED can be quoted as project work and no FCC ID is currently available. Both microwave switches are indoor products.
Key-card switches: confirm the receiver's default state, battery life and current rating before quotation; these points decide whether the installation is suitable and compliant.
TDL-9953: for seated or stationary occupants, agree a room test; a presence-sensing label is not a measured stationary-detection guarantee.
TDL-2025: check the connector, strip load, mounting position and PIR sensing field on the selected sample. The Type-C model is listed for 5 V DC; a Type-C connector does not establish USB Power Delivery support.
TDL-9953 and TDL-2025 documents: internal test reports are the stated documentation basis; certification-body certificates are not currently available for these families. Request the internal report for the exact suffix and confirm the documents required for your destination before ordering. Internal testing does not establish radio certification.
Ingress markings: read every IP number on this page the same way. Without a named test report beside it, it is a manufacturer's marking, not a tested rating. The X in IPX6 means the dust digit was never rated.
Certification: a lab quote is not a certificate. Treat coverage as confirmed only when an issued document names the exact model.
