A simple rain sensor that can be connected to one of the eight channels of the transmitter.
This gravity rain sensor is a reliable and practical device for precisely measuring rainfall. Its design is based on a container with sloped walls that allow rainwater to drain and measure its volume. The internal container corresponds to a rainfall of 0.28 mm per square meter and provides the user with readings in millimeters. The hollow bottom allows rainwater to drain away automatically, increasing the sensor's reliability.
