With the continuous optimization of wireless technology, wireless pressure sensors, wireless level sensors and wireless temperature sensors are widely used for remote monitoring of various adverse conditions. Based on the mature IoT cloud platform architecture and a variety of wireless transmission signals (NB-IOT, LoRa, 4G, Zigbee) can meet the needs of most measurement environments. According to the different use environment, those wireless sensor with standard and explosion-proof respectively, so as to meet the measurement needs of different media and fields. Unique low-power battery power (5 years) technology and automatic cycle storage can improve work efficiency and save costs. Remote monitoring of water (oil) level information on mobile phones and computers is the best wireless monitoring solution.
