While visiting the HK Electronics fair ODM came across this nice item which is particularly well adapted to an “over air-conditioned” environment like Hong Kong. That said, such a system is more critical in cold countries to protect young or aged persons. It could also be reprogrammed for different temperatures for Green houses. The Cold Alarm is a simple yet very useful product that warns you when the temperature drops. The easy functioning works with colour code flashing LED lights making these ideal for old age users.
- green light is on: safe environment, temperature is above 18°
- amber light is on: warning, your temperature is under 18° (but above 12°)
- red light is on: danger, your temperature is is 12°
- red light + alarm buzz: temperature dangerously cold under 7°
