50 of the most important Raspberry Pi Sensors and Components
The PIR motion sensor has some advantages over other similar products: besides the low price, a signal is sent only if something moves. This allows you to wait for signal flanks using the GPIOs. In addition, a resistance can be varied so that a signal is only sent when the movement is close, or changes that are already far away are perceived. In addition to outdoor projects, the PIR can also ...

Air Quality Sensor | MySensors Forum
moskovskiy82 For a fire smoke, you can use pretty much any gas or particle sensor there are a quite few gases formed during the burning process. MQ2 is highly sensitivity and has a fast response time. I can recommend it for a fire detection usage. However, I have been disappointed in MQ* sensors in general there are not accurate, require 24h heatup time, consume a lot of power etc.
