Review on 🌡️ HiLetgo 5pcs DHT11 Digital Temperature Humidity Sensor Module, 3.3V-5V, 20%-95% Humidity Measure Range, 0-50℃ Temperature Measure Range, with Dupont Wires by Chris Dildine

Super easy to use but almost unusable. DHT11 resolution is full degrees C with no other details. Absolute accuracy is also poor, but to be expected. Don't make my mistake and assume that readings like 23.6°C are possible - they aren't. From 22°C to 23°C in one step, no intermediate values. If that's okay for your application - and if moisture readings close to line noise are equally acceptable - then you can't beat the price. However, if you want to base some logic on these readings, I'd recommend the BMP08, DHT22, or DS18B20 instead.
