Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VDD | power_in | Positive power supply input. Operating range 3.0V to 5.5V. |+| 2 | C | passive | Reference capacitor pin. Connect the external reference capacitor (typ. 104 / 100nF) used by the capacitive detection front-end. |+| 3 | VSS | power_in | Ground reference (0 V) for the device. |+| 4 | OUT4 | output | Channel 4 water-level level-signal output. Outputs 1 when water is detected on CH4, 0 otherwise (active in one-to-one level output mode). |+| 5 | OUT3/RXD | bidirectional | Dual-function pin. In level output mode: OUT3 outputs channel 3 water-level status (1 = water, 0 = no water). In UART output mode: acts as UART RXD input. |+| 6 | OUT2/TXD | output | Dual-function pin. In level output mode: OUT2 outputs channel 2 water-level status (1 = water, 0 = no water). In UART output mode: acts as UART TXD output at 9600 baud, refreshed every 100 ms. |+| 7 | OUT1 | output | Channel 1 water-level level-signal output. Outputs 1 when water is detected on CH1, 0 otherwise. Also used to output calibration status pulses in BCD/test mode. |+| 8 | TEST | bidirectional | Test/calibration pin (input first, then output). Used by the host to trigger water-present/water-absent calibration and self-check routines via defined low/high pulse patterns after power-up. |+| 9 | SENS | input | Sensitivity selection input. Connect an external resistor to VDD to select one of 8 sensitivity levels (3.3K = highest, 10K, 18K, 27K default, 39K, 51K, 68K, 82K = lowest). Also requires a 100K resistor path to VDD; both resistors must be 1% tolerance. |+| 10 | OUTS | input | Channel output communication-mode select. 1 (float / H) selects one-to-one level output on OUT1-OUT4; 0 (tied to GND) selects UART output on TXD with all channel states refreshed every 100 ms. |+| 11 | TOPT | input | Test/calibration mode select. 0 = calibrate lower water level only; 1 = calibrate both upper and lower water levels. |+| 12 | CH1 | input | Water-detect sense channel 1 (lowest water-level channel). Connects to the corresponding copper foil on the water-level sense PCB. |+| 13 | CH2 | input | Water-detect sense channel 2. Connects to the corresponding sense-foil; tie to VSS (GND) if unused. |+| 14 | CH3 | input | Water-detect sense channel 3. Connects to the corresponding sense-foil; tie to VSS (GND) if unused. |+| 15 | CH4 | input | Water-detect sense channel 4 (highest water-level channel). Connects to the corresponding sense-foil; tie to VSS (GND) if unused. |+| 16 | Reserve | unconnected | Reserved pin. Leave floating on the PCB (do not connect). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | SOC Shenzhen SinOne Microelectronics |+| Package | SOP-16 |+| Category | Sensor |+| Pins | 16 |++## CAD (KiCad official)++- Symbol: `SCW8916B`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [SOC Shenzhen SinOne Microelectronics datasheet](docs/scw8916b-datasheet.pdf) (7 pp, sha256 `797e42d9aab4632e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
