This thermal imaging sensor has saved me hundreds in repairs (plus it works with iOS and Android)

Thermal cameras are very often $200 or more, but this inexpensive model from Thermal Master works for both iOS and Android and has a ± 3.6°F accuracy.

I finally found a thermal camera that works for both iPhone and Android (for only $129)
