In this article I show you how to connect and configure the temperature and humidity sensor DHT22 or DHT11 to HoneyPi. But first I will talk about the differences between DHT22 and DHT11. DHT22 vs. DHT11 The following data table shows that the DHT22 (white) is more accurate than the DHT11 (blue). The temperature range of the DHT22… Read More »
The BME680 sensor measures humidity, air pressure, temperature and air quality (IAQ). The BME280 ? is the little sister of the BME680 ? and does not measure air quality. The cost of the BME680 is about 20 Euro. The BME280 costs about 7 Euro. The BME680 requires the I2C bus of the Raspberry Pis. The I2C bus is… Read More »
The DS18B20 or DS18S20 is used as the outdoor temperature sensor. These temperature sensors measure the temperature quite accurately and can be placed inside the hive with a cable. The DS18B20 differs from the DS18S20 in that it is already equipped with a long waterproof cable. For simplicity’s sake we use the DS18B20 directly and invest the small… Read More »
