SCARLET TECH Wireless Anemometer WR-3 1Pc

Wireless Sensor:
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.
Handheld Receiver :
Large LCD display shows digital wind speed, temperature and beaufort chart clearly. Anti-slip rubber on two slides helps users hold the receiver in place during work. User-friendly interface and simple button design allow you to operate the device easily with only one hand.
Users can set wind threshold based on safety standards. When the wind exceeds wind threshold, an audible alarm will be triggered. The alarm will continue as long as high wind is detected. The alarm buzzer on top of the receiver can effectively warn users at the level of 90 dB.
Low Power Consumption :
We use innovative low-power consumption wireless technology on WR-3. The battery power consumption is only 20-30 uA in normal condition and 35 mA peak current during data transmission. 3.6V Lithium battery with 2600 mAh capacity can run the sensor for 3 years.
3-years long battery life reduces the maintenance cost significantly. Low battery indicator on the display monitor will show up when battery capacity is lowered than 10%.
