Pssopp Outdoor Rain Gauge, RS485 Aluminum Alloy Rainfall Measurement Monitoring Tool for Yard

Spec: Item Type: Rainfall Sensor Material: Aluminum alloy Weight: Approx. 524.00g/18.48oz Output RS485 Power Supply Voltage: 9 to 30V Sensor Cable Length: Approx. 2.5m/98.4in (±5cm) Product Size: Approx. 85x78mm/3.3x3.1in Hole Spacing: Approx. 72mm/2.8in Rainfall Mouth Diameter: Approx. 60mm/2.4in Measurement Range: 0 to 4mm/min (measurements may become inaccurate beyond this rainfall intensity) Resolution: 0.03mm Accuracy: ±4% (static test indoors, rainfall intensity at 2mm/min) Protective Level: IP65 Power Consumption: ≤0.24W (12V DC, current less than 20mA) Operating Temperature: 0 to 65℃ Operating Damp: 0 to 99%RH (non condensing) Wiring: Red Cable: Power positive Black Cable: A+ Yellow Cable: B- : Power negative CRC Check Steps: 1. Initialize a 16-bit register to hexadecimal , 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). How to Use: According to appropriate voltage for use packing list: 1 x Rainfall Sensor 1 x User Manual Note: Please check the packaging for any damage and verify that the product model matches the one you selected. Do not connect the wires

• COMPACT AND LIGHTWEIGHT: With no moving parts, the rainfall amount sensor module is compact and portable, easy to install, less susceptible to wear, and simple to maintain.
• WIDE APPLICATION RANGE: Widely used in industries and fields such as smart meteorology and environmental guard, smart irrigation, marine navigation, automated weather stations, automatic door and window, and geological disaster monitoring.
• PRECISE RAINDROP MEASUREMENT: Utilizes a drip sensing design principle with a special internal structure for accurate control of raindrop size, combined with optical sensing principles for raindrop counting to measure rainfall volume.
• RS485 OUTPUT The rainfall monitoring operates on 9 to 30V power supply voltage, providing precise measurements and high reliability for data transmission.
• ALUMINUM ALLOY CONSTRUCTION: Made of premium aluminum alloy material, the rainfall sensor is sturdy and long lasting, capable of operating normally in high temperature and damp environments.
