Description
This Analog Temperature Sensor consists of a metal temperature probe and a 58cm long cable, featuring a wide temperature range in -25°C to 125°C, suitable for immersive temperature detection. If you want to use it with Arduino, simply connect it as the picture below
Features
- Waterproof
- Linear resistor
- Easy to use
※請注意，電纜部分不能放在高於105°C的溫度下。
