Adafruit Industries, Unique fun DIY electronics and kits Adafruit STEMMA Soil Sensor I2C Capacitive Moisture Sensor : ID 4026 Most low cost soil sensors are resistive style, where there''s two prongs and the sensor measures the conductivity between the two. These work OK at first, but eventually start to oxidize because of the exposed metal.
Jul 29, 2012· Good for 0100% humidity readings with 25% accuracy. Good for 40 to 80°C temperature readings ±°C accuracy. No more than Hz sampling rate (once every 2 seconds) Body size x 25mm x 4 pins with " spacing. As you can see, the DHT22 / AM2302 is a little more accurate and good over a slightly larger range.

A guided tutorial for building a CO2 concentration liveplot. See the co2meter documentation for more details if you don’t use Ubuntu.. I was only able to get this working by connecting to the USB interface as root, it’s probably possible to adjust these rules to make the interface available to all users.
SparkFun SCD30 Arduino Library. An Arduinolibrary for the SCD30 CO2 sensor from Sensirion. The SCD30 is a high quality NDIR based CO₂ sensor capable of detecting 400 to 10000ppm with an accuracy of ± (30ppm+3%). In order to improve accuracy the SCD30 has temperature and humidity sensing builtin, as well as commands to set the current altitude.

Jul 25, 2021· The SCD30 is an NDIR sensor, which is a ''true'' CO2 sensor, that will tell you the CO2 PPM (partspermillion) composition of ambient air. Unlike the SGP30, this sensor isn''t approximating it from VOC gas concentration it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...
Aug 04, 2017· This short tutorial shows how to build simple CO2 meter using CJMCU8118 board and Raspberry Pi 3. This board uses CCS811 sensor. This sensor supports intelligent algorithms to process raw sensor measurements to output a TVOC value or equivalent CO2 (eCO2) levels, where the main cause of VOCs is from humans. CJMCU8118 includes HDC1080 sensor.

Oct 29, 2020· It uses an esp8266, a SGP30 eCO2 sensor and a DHT11 for humidity temperature. A high CO2 concentration means you should ventilate the room (and so, indirectly can help to limit COVID19 indoors). SPG30 doesn’t detect CO2 but can make a « equivalent CO2 » (not great but sensor is cheap, about 10 €). It displays value on an OLED screen ...
Feb 02, 2021· Carbon dioxide, aka CO 2, is a gas that is an essential part of the Earth''s atmosphere and life in general. However, while essential, it can have negative effects when concentrations exceed certain level. It can impact the entire planet via global it can also have very local effects, for example on indoor air levels of CO 2 can lead to reduced cognitive ability and ...
