Wireless Aquarium Thermometer System

The Wireless Aquarium Thermometer System transmits temperature readings from a waterproof sensor inside the aquarium to a standalone LCD receiver unit that can be placed anywhere within the wireless range — typically 15–30 metres. This allows the keeper to monitor tank temperature from a desk, sofa, or across a fish room without approaching the tank.

The receiver displays current temperature, minimum and maximum readings since the last reset, and activates an audible alarm if the temperature exceeds configurable high or low thresholds. Multiple sensors can often be paired with a single receiver for monitoring several tanks simultaneously.

Ideal for large fish rooms, hobbyists who monitor tanks from a distance, and anyone who wants overnight temperature alarms without a smartphone app or smart-home system.
