SM-C3H8-P01 Propane Module

[Detection gas]:propane (liquefied gas)

[Type]:Figaro TGS2618

[Response time]:≤10 s

[Recovery time]:≤10 s

[Size]:32×25×15mm

[Features]:safe and reliable, small size, easy to install

[Introduction]:This module is widely used in the whole machine development of household gas leakage alarm and gas leakage detection components. The input power supply, induction probe and signal output in the sensor are completely isolated. Safe and reliable, small size, easy to install. This product adopts high-sensitivity semiconductor probe with stable signal and high precision. It has the characteristics of wide measurement range, fast response speed, convenient use and easy installation.
