SONOFF Temperature Sensor DS18B20
The DS18B20 temperature probe with waterproof RJ9 connector is used to measure the temperature of an environment (including aquatic environments) in a simple and accurate way.
After placing the probe on a device, all settings and readings are associated with that device and can be used to create various bespoke scenarios. For example, whenever the probe detects an aquarium temperature below 12ºC, it activates the heater, among many other applications.
