Many setups and projects can be improved by monitoring pressure, temperature and humidity. There are a range of sensors that can be used and the Pilot-CAN supports a number of them including the Sensirion SHT range of sensors. There are many other sensor options included in the yellowcog software library. This all makes it simple to add, for example, in cockpit temperature and humidity reading and have these logged by a CAN data logger.
There are many bespoke, Temperature/Humidity and Pressure products, fist check the Temperature (and pressure) Module.
