A wireless outdoor air quality monitoring board with environmental and particulate sensors and a microphone.
Enviro Urban is an all in one board for checking up on all the airborne nasties that can occur in built up areas. There's a BME280 sensor for measuring temperature, humidity, and pressure, a microphone for noise monitoring and a pre-installed PMS5003I particulate sensor. Particulate matter is made up of tiny particles that are a mix of sizes and types, like dust, pollen, mould spores, smoke particles, organic particles and metal ions, and more. Particulates are much of what we think of as air pollution.

Can be powered by a 3 x AA battery pack, which fits neatly behind the board.
Any battery pack that can supply between 2V and 5.5V will work though - 2 or 3 alkaline AA or AAA cells, 4 rechargeable NiMH cells or a single cell LiPo.
