Weight: Approx. 272.00g / 9.59oz Calculation formula: 0-5V: F=V/5 A+B F: Represents the wind speed value, m/s; V: Sensor output voltage value, V; A: Sensor range width (upper range minus lower range); B: The minimum range value of the sensor (lower range limit); Wiring method (wire sequence is respectively): Red line: power supply positive (output signal voltage) Black line: power supply negative (output signal voltage) Yellow line: signal (output signal voltage) Distribution diameter: Approx. 63mm / 2.48in Installation diameter: Approx. 3.2mm / 0.13in Aviation plug diameter: 15mm/0.59in (it is recommended to reserve 25mm for wiring, wire first, and then install and fix the sensor) Troubleshooting: 1. The wind blades do not rotate properly and have a large lag. Due to long term use, there may be foreign objects or jamming inside the bearing. Please send the sensor back to the company for processing; 2. The display value of the analog signal instrument is incorrect. Possible wiring issues or serial port failures may result in the inability to obtain correct data. Please check if the wiring is correct and secure, if the serial port is occupied, and if the serial port settings are correct; Package List 1 x Wind Speed Sensor with Cable
