Thermometer Temperature Controller W1209

The W1209 Temperature Controller Module is a digital thermostat board that can automatically turn a device ON or OFF based on temperature. It includes a 3-digit LED display, relay output, and an NTC temperature probe, making it ideal for heating or cooling control systems.

Unlike simple sensors (like DS18B20), this module can directly control appliances using its onboard relay.
