Gravity - hydrogen phosphide sensor.

Product compatible with Arduino, ESP32, Raspberry Pi

The manufacturer has prepared a detailed user guide, which includes, among other things, connection instructions and sample program code.

Czujniki posiadają ten sam format danych dzięki czemu mogą współpracować równolegle.

The sensors have the same data format so they can work in parallel.

A series of pre-calibrated sensors from DFRobot

DFRobot has developed a series of sensors that have been factory calibrated. The series consists of up to 12 modules, which enable the detection of the most common gases. Among them we can find CO, O2, NH3, H2S, NO2, HCL, H2, PH3, SO2, O3, CL2, HF sensors.

In addition, the sensors in this series operate in the same way and have the same data format, so they can work in parallel.

Phosphorus in the air?

Hydrogen phosphide PH3 has strong toxic properties and is an extremely flammable gas. It is used to gasify grain stores and wooden structures in buildings, animal food and tobacco leaves, and fruits and vegetables. Neutralization of the gas effect can be done, for example, by using a long incubation period.

Suggested applications

  • Industrial phosphine detection
  • Mining phosphine detection
  • Environmental protection in general
  • Intelligent agriculture
