Sometimes it is not necessary to monitor the absolute air pressure but we need to know the difference of pressures in different points. One example may be before and after a valve in a pipe. If the valve is fully open, the pressure on both sides should be the same. If there's a difference in the pressure, it could be the valve isn't fully open or there's a blockage.

Differential Pressure Sensor has two air pressure inputs. It monitors the pressure difference between these two inputs and put the value.

Differential Pressure Sensors can be used in home and industrial environments for applications such as offshore and subsea gas processing, and remote heating systems.

Dragino's Wireless Differential Pressure Sensor includes various model to cover LoRaWAN wireless transmission and different range of pressure measurement.

TrackerD-LS is an Open Source LoRaWAN Asset Tracker based on ESP32 MCU and Semtech LoRa Wireless Chip. It can get the location data via GPS and set it to IoT server via LoRaWAN network.

TrackerD-LS supports Motion Detection, when there is motion, TrackerD-LS can send data more frequently and it will save power when no motion is detected.

The LoRa wireless technology used in TrackerD-LS allows the user to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. It targets professional tracking services.

When there is no LoRaWAN network, TrackerD-LS can save the location data. It will send these data to IoT server when there is LoRaWAN network coverage.

TrackerD-LS is equipped with a 3000mAh Li-ion rechargeable battery + Solar Panel which let the device can be used for many years. Each TrackerD-LS has a worldwide unique OTAA keys to join the LoRaWAN network. 

TrackerD-LS is program friendly. Developers can use Arduino IDE to customize the software of TrackerD-LS to fit their IoT solution.
