Waterproof 4-20mA Liquid and Gas Pressure Sensor LoRaWAN NB-IoT LTE CAT-MWaterproof 4 20mA Liquid and Gas Pressure Sensor LoRaWAN NB IoT LTE CAT M These Waterproof Liquid and Gas Pressure Sensor series have LoRaWAN, NB IoT and LTE CAT M versions for Internet of Things solutions. It can measure Air or Water pressure and upload the sensor data wirelessly to the IoT server cloud. It supports BLE configuration and wireless OTA update which makes it easy to use. It is powered by an 8500mAh Li SOCI2 battery, it is designed for

The TPS61230A device is a high efficiency fully integrated synchronous boost converter

HOW DOES IT WORK

2 x Door + Window Sensor    >

The measured temperature is calibrated in degrees Celsius

One connector is used to connect an external voltage source

1 slot for WisBlock IO extension modules

effectively suppress surge voltage and transient spike voltage in the circuit
