We’re beginning an exciting project here at LAR to build autonomous sensors for indoor and outdoor air quality networks. Below is an image of a Raspberry Pi computer (left) attached to a cellular phone. The green cellphone antenna and the white GPS antenna are connected to the phone. The little red square on the right is actually a temperature, pressure, and humidity sensor. We’ll be pulling this together as a single package soon, and will be testing how the sensor acquires data and transfers it back to a server here in the lab. We hope to integrate ozone, carbon monoxide, and particulate matter sensors too. Cool stuff!
