W1209 Digital Thermostat High Precision Temperature Controller Switch  -50° to 110° C with Digital LED Display 


The W1209 is an incredibly low-cost yet highly functional thermostat controller. With this module, you can intelligently control power to most types of electrical devices based on the temperature sensed by the included high-accuracy NTC temperature sensor. Although this module has an embedded microcontroller no programming knowledge is required. 

3 tactile switches allow for configuring various parameters including on & off trigger temperatures. The onboard relay can switch up to a maximum of 240V AC at 5A or 14V DC at 10A. The current temperature is displayed in degrees Centigrade via its 3-digit seven-segment display and the current relay state by an onboard LED.
