Peace of mind
"Very pleased with the alarm. It does exactly what I wanted and I sleep well at night."
Passive Solar Application
"I use these for passive solar collector heat monitor and alarm. When temperature at top of collector reaches 35 degrees Celsius the alarm sounds. Time to open airways and turn on fan to heat house. Will eventually automate process to have alarm trigger actuators to open the airways and a switch to turn on fan. Excellent monitor and alarm at a good price."
Power Outage Helper
"When the power fails it is important to know what your freezer/refrigerator temps are without opening them. That way you can fire up the generator just when needed. This little sensor does the job with the added advantage of an alarm."
