Hunan Aerospace Magnetoelectric sss-666 tilt sensor

u is fixed on the inside of the smart manhole cover with screws. It is easy to install and adapts to the intelligent transformation of most manhole covers on the road surface?

uBy monitoring the flip and motion trajectory analysis of the manhole cover,it is determined whether the manhole cover is opened abnormally. Once the abnormality is determined,an alarm message is immediately sent to the background.

uTheadvanced trajectory analysis algorithm ensures accurate judgment of the status of the manhole cover. When a large vehicle rolls over and causes the manhole cover to vibrate,the alarm will not be falsely triggered. The overall false alarm rate is less than 2 in 1,000.

uLowpower consumption design,under normal working conditions,status information (remaining voltage,device number,signal strength,etc.) can be sent to the background regularly. It can be sent3,000times without replacing the battery,and the standby working time is no less than3years.

uSupportsBluetooth/NBcommunication,and can be usedfor arming,disarming,and parameter configurationthrough the mobileAPP.

uSupportsaccess to all manhole cover monitoring platforms or digital urban management platforms on the market.

uAppearance is sealed,corrosion-resistant,wear-resistant,pressure-resistant,shock-resistant,and waterproof gradeIP68.

uWorkingenvironment temperature-40 ℃ -- 80 ℃.
