2. Sensor Placement (Outdoor Unit)

For accurate rainfall readings, proper placement of the outdoor sensor is crucial.

• Place the sensor 1-2 meters (3-6 feet) above the ground.
• Ensure the sensor is in an open area where rain can fall freely from all sides, away from obstructions like trees, buildings, or overhangs.
• The transmitter (433.92MHz RF transmitting frequency) should have a clear line of sight or minimal obstructions to the indoor display for optimal wireless communication.
