W1209 thermostat module has a temperature sensor, keys, led
display, relay and requires dc 12v power supply. It is an
affordable, good quality thermostat controller. Thermostats are
devices that sense the temperature of a system so that the
temperature is maintained at the desired set point or near to it.
Ntc temperature sensor allows the module to intelligently control
varied electrical devices based on the temperature. The relay can
operate at voltages up to a maximum of 240v ac at 5a or 14v dc at
10a to power on. The temperature is displayed in degree
centigrade and with the help of 7-segment display and the relay,
the state is displayed with the help of the led present on the
w1209 module. Specification:- temperature control range: -50 ~
