Item Type: Rainfall SensorMaterial: Aluminum alloyWeight: Approx. 524.00g/18.48ozOutput Signal: RS485Power Supply Voltage: 9 to 30VSensor Cable Length: Approx. 2.5m/98.4in (±5cm)Product Size: Approx. 85x78mm/3.3x3.1inHole Spacing: Approx. 72mm/2.8inRainfall Mouth Diameter: Approx. 60mm/2.4inMeasurement Range: 0 to 4mm/min (measurements may become inaccurate beyond this rainfall intensity)Resolution: 0.03mmAccuracy: ±4% (static test indoors, rainfall intensity at 2mm/min)Protective Level: IP65Power Consumption: 0.24W (12V DC, current less than 20mA)Operating Temperature: 0 to 65℃Operating Damp: 0 to 99%RH (non condensing)Widely Used in: Smart , meteorological environmental guard, smart irrigation, ship navigation, automatic weather stations, automatic door and window, geological disasters, etc.Wiring:Red Cable: Power positiveBlack Cable: A+Yellow Cable: B-: Power negativeCRC Check Steps:1. Initialize a 16-bit register to hexadecimal FFFF, referred to as the CRC register.2. XOR the first 8 bits of data with the low bits of the CRC register, and store the result back in the CRC register.3. Right shift the content of the register by one bit (towards the lower order bits), fill the highest bit with 0, and check the lowest bit.4. If the lowest bit is 0: repeat step 3 (shift again); if the lowest bit is 1: XOR the CRC register with the polynomial A001 (1010 0000 0000 0001).5. Repeat steps 3 and 4 for a total of 8 shifts, processing the entire 8 bits of data.6. Repeat steps 2 to 5 for the next 8 bits of data; the final CRC register obtained is the CRC code (with low byte first and high byte last).Troubleshooting:1. Incorrect displayed value on the instrument during RS485 output. Possible causes include wiring issues or communicating port faults leading to incorrect data retrieval. Check for proper and secure wiring
