Introducing the (new model) RG-9 Rain Detector. Specially design to detect raining activity.
Simple to use, easy maintenance.
Highly responsive sensor detects raining activity fast.
Rain Sensor Configuration
DIP Switches on the rain detector sensor board provides you with options to set the sensor’s sensitivity (DIP switch 1, 2) and the kind of output response (DIP switch 3, 4) that you want.
| 1 | 2 | 3 | 4 | Function |
| OFF | OFF | Sensitivity 1 (sensor gets triggered with rain drop) | ||
| OFF | ON | Sensitivity 2 (sensor gets triggered with very light rain) | ||
| ON | OFF | Sensitivity 3 (sensor gets triggered with medium rain) | ||
| ON | ON | Sensitivity 4 (Rain sensor gets triggered with heavy drop) | ||
| OFF | OFF | OUT is switched off immediately when there is no raining activity. | ||
| ON | OFF | OUT is switched off when there is no raining activity for the last 5 minutes. | ||
| OFF | ON | OUT is switched off when there is no raining activity for the last 10 minutes. | ||
| ON | ON | OUT is switched off when there is no raining activity for the last 15 minutes. | ||
Pin Out (Wiring Connection)
J1 Connector is enough to interface the RG-9 for rain detection operation.
| J1 Connector | |
| Pin 1: | OUT (Open collector output pulled to ground when rain is detected) |
| Pin 2: | V+ 5 to 16Vdc (Power Input) |
| Pin 3: | GND (Ground) |
J2 Connector (J2 header) can be used if you need to have more control or access to the rain activity information from the serial interface.
J2 Connector is a 2.54mm pitch 10 pins header.
| J2 Connector | |
| Pin 1: | GND (Same as J1 GND) |
| Pin 2: | V+ (Same as J1 V+) |
| Pin 3: | OUT (Same as J1 OUT) |
| Pin 4: | Serial OUT |
| Pin 5: | Serial IN |
| Pin 6: | — |
| Pin 7: | MCLR |
| Pin 8: | V+ 3.3V |
