REMOTE TEMPERATURE MONITORING An alarm. When it's 40C down here and I need to charge batteries, I want an ALARM when case temperatures reach 50C. If a charger reaches 65C I want an alarm to scream, not just a gauge. This sending unit got me thinking that a 5-satellite alarm system would be inexpensive. Cheap and easy to build. When my toad or rig radiator gets too hot I want an ALARM not a doggone needle or numbers to hover over. BEEEEEEEEP!!! Respond or lose lots of money.
