Rain Sensor

This rain sensor measures the amount of rainfall at its location using a tipping bucket mechanism, reporting the quantity within a 15-minute interval with an accuracy of 0.5 mm of water column and additionally provides the temperature. In the event of heavy rainfall exceeding 15 l/h, a heavy rain alarm is triggered promptly. Both the heavy rain threshold and the measurement interval are configurable.

The sensor is powered by two AAA batteries. The supplied VARTA batteries allow for an approximate runtime of about 2 years. A low battery level is wirelessly reported, enabling the replacement of batteries before the device shuts down.

LoRaWAN Rain Level Sensor 'LoRain'

The device is controlled through LoRaWAN commands, operating as a LoRaWAN Class A device. The use of the device requires LoRaWAN network coverage, such as 'The Things Network.' Otherwise, a dedicated LoRaWAN gateway must be installed and operated.

The device is entirely open-source. Hardware and firmware source files can be downloaded from

Rain Level Sensor WiFi

The device communicates via WLAN, either to the Aqua-Scope Cloud and consequently to a free app on mobile phones or PCs, or it can communicate via MQTT to a server of your choice. Additionally, it supports communication via a 'Webhook,' sending data as a JSON object to a Smart Home Gateway.
