FR-04 rain sensor for home automation projects

Raindrop sensor for home automation and ad-hoc projects, can be used to track a variety of weather conditions. The FR04 a plate made with high quality double-sided materials and with the surface of the nickel plating treatment, against rust, great conductivity, superior performance and great longevity. The comparator output: the signal is clean, waveform, the driving capacity more than 15 mA. The result in the form: digital switching outputs (0 and 1) and the analog voltage output AO.

Specifications:

• Input voltage: 3 ~ 5 VDC
• GDN: Negative
• DO: TTL switching output interface
• AO: Analog Output Interface
• Dimensions: 50 x 40 mm
