FAQ

1. What is Phosphine and why is it dangerous?
Phosphine (PH₃) is a highly toxic and flammable gas often used in fumigation and semiconductor manufacturing. Continuous monitoring helps prevent poisoning and ensures workplace safety.

2. How does the PH₃ Sensor work?
It uses an electrochemical or MEMS-based sensing element that reacts specifically with phosphine, converting gas concentration into a measurable electrical signal.

3.  Can the sensor be used outdoors?
Yes, when integrated into a properly sealed housing. It’s suitable for semi-outdoor or industrial applications with moderate humidity.

4. Is calibration required before use?
Each sensor is factory calibrated, but periodic recalibration (every 6–12 months) is recommended for best accuracy.

5. How long does the sensor last?
Under normal conditions, the operational lifespan is at least 24 months. Lifespan may vary depending on exposure to high gas concentrations or humidity.

6. How can I interface this sensor with a microcontroller?
It supports analog, UART, or I²C output — compatible with Arduino, Raspberry Pi, and most IoT platforms.
