MH-Z19 CO2 concentration Sensor MH-Z19  is a small, low-cost, weigh 15g CO2 sensor module product by  郑州炜盛电子科技 . You can buy it at an online shop like  eBay  or  aliexpress  about 20$. The electrical interface of this sensor is compatible with Raspberry Pi. So you can make your D.I.Y. CO2 Monitor with MH-Z19, Raspberry Pi. The normal CO2 concentration is about 400ppm. On a global scale, this value is sensitive to the effect of the activities of the plants, seasonally it gets lower in summer due to vigorous plants photosynthesis and getting higher in winter, and the long-range trend is continuing to rise linearly. The Japanese Meteorological Agency reports CO2 concentration chart continuously as hire . It indicates a clear trend of rising. On your room-scale, in a closed room with 2 people, CO2 concentration rise up to 1,200ppm soon and keep falling slowly after 1 person go out. In a high CO2 concentration room as 1200ppm, somebody ca...

DHT22 (AM2302) temperature & humidity Sensor Though  DHT22 (another name AM2302) sensor is small and low-cost, but have a decent quality of precision of me asuring temp/humidity. You can buy the ready to use breakout of DHT 22 for 3 - 4$ from  eBay . Why measure the room humidity as well as temperature Not only to get comfortable air but also to measure and control humidity has a lot of purposes, for example: - In high humidity rooms like summer or monsoon season in Japan, where I live in, It often grows the mold everywhere on the wall, clothes, food and so on. The mod can't be active under low relative humidity . I'm controlling my room to keep relative humidity under 60% to block to grows the mold. The filamentous fungi , which is many of the causes of plant disease , is in the same family of mold, so a lot of plant disease also can avoid by humidity control.  - Some plant is known that they close there pore under hight Humidity Deficit (I'll...
