T1820B from Mysentech, in a TO-92S. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference pin for the sensor (地), listed in the page 3 pin table for the TO92S package. |
| 2 | DQ | bidirectional | Single-wire (One Wire) digital bus pin, open-drain with an external pull-up of about 4.7 kΩ (1 kΩ to 10 kΩ allowed per the electrical table), with VIL max 0.3VDD and VIH min 0.7VDD, and VOL max 0.4 V at IOL = -3 mA. |
| 3 | VDD | power_in | Supply pin with a stated operating range of 1.8 V to 5.5 V (3.3 V typical), and 3.3 V or higher is recommended for long cables or multi-drop bus operation. |
