WR-3 applies state-of-art 433/868/900 MHz radio frequency wireless technology to ensure better performance for barrier penetration and achieving long range transmission. The ultra-long 400 meter transmission distance makes WR-3 a perfect gadget to help users monitor wind speed on crane/lift/towers and prevent accidents from high wind risks. Data transmit rate: every 2 seconds.
The sensors automatically send data when wind cups revolve. It goes to sleep mode when wind cups stop for more than 6 hours to save power consumption.
