# MY18B20LD10

**Mysentech** · Temperature and Humidity Sensor · TO-92L

MY18B20LD10 from Mysentech, in a TO-92L. 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 | GND | power_in | Ground reference for the device. Connect to system ground. |
| 2 | DQ | bidirectional | 1-Wire single-bus digital data I/O. Open-drain / three-state, requires an external pull-up resistor (typ. 10 kΩ, or 1 kΩ for long-cable / multi-drop configurations). Carries all command, ROM ID and temperature traffic; can also parasite-power the device on short lines. |
| 3 | VDD | power_in | Supply voltage input, 1.8 V to 5.5 V (recommend ≥3.3 V for long-cable or multi-drop operation). Typical standby current 0.2 µA @5 V; average 5 µA @1 Hz sampling. |
