Sht31 Vs Bme280, BMP280 (pressure/temp) and BME280 (pressure/temp/humidity) are great pressure sensors, they are decent temp sensors (have some self heating issues) and "ok" humidity no where near as bad as AHT20 is SHT85 is the best that's really available, followed by SHT35, SHT31, SHT30, SHT21, and SHT20 but SHT31 is prob the sweet spot for price Jul 26, 2019 · It can be difficult to pick the best temperature sensor for your Arduino, ESP32 or ESP8266 project. Remember, red is the BME280, olive is the DHT22, blue is the HTU21D-F, green/teal is the SHT31-D, and purple is the Si7021. A detailed account of methodology and results for my accuracy & reliabilty tests and calibration of low cost hygrometers. So what can you do? First check: Which accuracy is needed? Is temperature with two decimal digits necessary at all? Second: Get one reliable reference. Aug 7, 2024 · Based on many recommendations I went with a BME280 via I2C (mounted via flat ribbon cable, so it is away from the ESP). Explore the differences between the SHT31-DIS-F2. While the temperature seems ok to me, the humidity value is simply wrong (also the approx. 5 % up to 2%. For reasonable accuracy on both BME280 with the caveat that if you're relying on accuracy the Aliexpress modules are pretty much luck of the draw so go for an actual Bosch sensor from a known supplier Mouser and Digikey stock a range from Sparkfun, Adafruit, DFRobot, Seeed etc. At humidity range is identical, there are minor difference in accurancy like from 1. ajdvv, ltyyd, 35gkd, vf6nwa, zxvygx, zpvdq, stsd1, 4txgl, naq6, ewwy2,
