Thermal Sensor Relay Module 5V Temperature Control Switch Board | Automatic Heat Sensor Relay 10A

Thermal Sensor Relay Module 5V Temperature Control Switch Board | Automatic Heat Sensor Relay 10A 

The Thermal Sensor Relay Module is an automatic temperature control switch board designed to turn electrical devices ON or OFF based on heat level. It uses a thermistor temperature sensor to detect temperature changes and activates the relay when the set threshold is reached.

The trigger temperature can be adjusted using the onboard potentiometer, allowing precise control for different applications. This module can directly control AC or DC loads such as fans, heaters, motors, lights, pumps, and other electrical devices.
