1.King Dimension: 54X40mm
2.PCB Board Dimension: 30X16mm
3.Voltage: 5V
4. The output in the form: digital switching outputs (0 and 1) and analog AO voltage output;
5. A fixed bolt hole for easy installation
6. Power indicator, the output signal LED indicator.
7. TTL-level output, TTL output valid signal is low. Driving capability 100MA so, can directly drive relays, buzzer, a small fan, and so on.
8. Sensitivity can be adjusted via potentiometer
9. LED lights up when there is no rain output is high, raindrop up, the output ground level, LED light.
10. Raindrops and control panels are separate, easy to wire leads.
11. A large area of rain board, more conducive to detect rain.
12. Board with positioning holes to facilitate installation
13. Wide voltage LM393 comparator
