A Temperature Sensor Module (KY-001 3pin DS18B20) is a device that can be used to measure temperature. The module is based on the DS18B20 digital temperature sensor, which is a 1-wire device that can measure temperatures from -55°C to 125°C with a resolution of 0.5°C. The module has three pins: VCC, GND and DQ, and it communicates with the host microcontroller through a single pin. The KY-001 is the model number of the module, the 3pin indicates that it has 3 pins, and DS18B20 is the model number of the temperature sensor chip. These types of temperature sensor modules can be used in various applications such as HVAC, industrial control, and home automation. 1. Temperature Measurement Range: -55 celsius ~ 125 celsius . 2. Range Accuracy: ±0.5 celsius . 3. Working Power Supply: DC 3 ~ 5V. 4. Measurement results in 9 ~ 12 digital quantity way serial transmission.
