| Arduino Info USB/FTDI programmer Add libary Remove libary RF transmit / Recive 315 or 433 Mhz CD4051B - 8 port analog multiplexer 74hc595 - 8 port shift register - output 1-Wire ® Temperature (DS18B20) i2c bus + scanner i2c Barometric Pressure + Temp(BMP085) i2c LCD 1602 Display SingleBus Temperature + Humidity(DTH11 + DTH21 + DTH22) |
Arduino DHT 11 + DHT 21 + DHT22 Humidity and Temperature Sensor(DHT11+DHT21+DHT22)Using cheap DHT22 Temperature and Humidity Sensor is prefered.
Recommended standard reusable hardware
Use donate button if you like my guides, or if you want a new guide ( See missing work ). Data sheet DHT11 Data sheet DHT21 Data sheet DHT22 
Here sample setup. My sample config require you add Libary - - Guide I have tried several libarys, some gave error with negative values. Here is my prefered.
