Hi I am looking for different IP based and relay -Normal Open/Normal close on event based sensors. Especially for home gas sensors. There number of them as a consumer products which you can use if modified. Found one by RLEtech HD150 but it cannot feel Propane Gas and Methane Gas and expensive. If any one knows affordable relay terminal based GAS sensor please let me know. Same question for for soil humidity sensors
