Temtop Air Quality Monitor with Indoor Thermometer & Thermo-Hygrometer – PM2.5, AQI, Temperature and Humidity Meter for Home, Office, Nursery, School, 60-Day Battery Life

Includes pm2.5. It will monitor other things like humidity and temperature, but we care about pm2.5 reading most. I got something like this, but with Bluetooth option so I can look at historical readings. https://www.amazon.com/Temtop-Outdoor-Thermometer-Hygrometer-Quality/dp/B0CLCL9HH4/ref=mp_s_a_1_4?crid=3OR7QOHSKB4BB&dib=eyJ2IjoiMSJ9.y05ACs6ld4QDGPKKtGNzqX-lEJmz3PDttFwISDJyiYh2Sce4sbMNrfX2C0UJq0qOEWy7fuhsvecjGrYnoswKPSDhn0xZnTr56iZn5ldnqOp40g07g-eyLoDsuLTgaSzqaN3s7PQ5sWqlkNrtibLxxgPODgRcMXhOtb1Ec1dhpE7xDn2F4t-8Ruos3ZkJ2Nnxx1wKhFCvxpDfRCnBn81omg.-6QixAMk7CWHmUBFZyffYnPjogXJGAw-yQmjMhDQUmQ&dib_tag=se&keywords=temtop+pm2.5&qid=1781648783&sprefix=temtop+pm%2Caps%2C232&sr=8-4
