Formaldehyde Gastec Detector Tube Environmental

Formaldehyde Gastec Detector Tube Environmental

The permissible formaldehyde exposure levels tend to differ from country to country. For instance, in Japan where GASTEC detector tubes originated, an average level of 0.1 mg/m 3 (equivalent to 0.08 ppm at 23℃) over a 30-minute period is allowed. * Formaldehyde detector tube No.91P (0.02 - 0.4ppm),91PL (0.02 - 0.2ppm)

    To do so, we will first employ a gas sensor module, MQ2, and the temperature and humidity sensor DHT22 (AM2302). Both will be read by the first ESP32 LORA, which will function as the Sender, and will send an alert to the second ESP32 Lora, which will be a Receiver. This provides safety for a situation such as a gas leak, for example.
