ER-G-02 Low Cost Wireless Tilt Sensor support band8 frequency band, UDP protocol stack, support serial port, meet NB-IOT standard, support data transparent transmission.
Rechargeable lithium battery with low-power optimization mechanism and can automatically enter low-power sleep mode. It can be used for several years without replacing the battery. It can be charged to meet the needs of high-precision long-term monitoring.
With remote control and management functions, data can enter the cloud directly.
All modules are designed with ultra-low power consumption, the sensitive mechanism adopts the latest technology, and the inclination unit of the MEMS production process is small in size, low in power consumption, high in consistency and stability. Because it is a digital inclination sensor module, linearity Easier to get corrected. The working temperature reaches industrial grade -25 ℃ ～ + 85 ℃. The entire sensor node has very low current consumption, is easy to install and maintain, and greatly reduces the use cost.
