1. using high sensitive thermistor testing environment temperature, with authentic quality relay, can directly control ac or dc load, Maximum load capacity: normally open interface communication 0 v - 250 v / 10 a, dc 0 v, 30 v / 10 a.
2. can be through the potentiometer to adjust temperature threshold, when the environment temperature is higher than the threshold, relay, absorption temperature below this threshold, relay release;
3. Intelligent control design, after the relay operation, automatic threshold, solves the problems of critical value repeated action;
4. Module with functions of meter, the reverse power will not damage the module;
5. equipped with a power indicator light (red), relay status indicator light (blue)
6. modules, working voltage is 5 v, 12 v is optional, please indicate the user when the choose and buy;
7. is equipped with four fixed bolt hole, convenient installation;
8. module size: 5.0 cm * 3.0 cm * 3.0 cm;
9. module with a free take 30 cm thermal sensor lead;

1. a thermistor module is sensitive to the environment temperature, commonly used to detect the change of the temperature of the surrounding environment;
2. module in the environment temperature is higher than the setting threshold, relay or absorption, common and often start through to disconnect) (and normally closed end, when the environment temperature is lower than the setting threshold, relay disconnect, common and often start off (connected with normally closed end);
3. public side, normally open, normally closed three ports is equivalent to a double switch, relay coil electricity, public end and beginning conduction, often without electricity, public end with normally closed end conduction;
