For this project you will need: an Orange Pi Plus 2e (or Raspberry Pi. These sensors are very basic and slow, but are great for hobbyists who want to do some basic data logging. FTCBlock 3pcs DHT11 Temperature and Humidity Sensor Module for Arduino Raspberry Pi Low Price. They have different range of measurement and accuracy. In this tutorial, we are going to use Raspberry Pi and DHT11 with Cayenne. You can use this project as designed: a simple weather station for your home. temperature and humidity in a less cost. dht(sensor,blue). In this article, we will be teaching you how to interface a DH11 sensor with your Raspberry Pi which will display its readings on a 16×2 LCD screen. Pieces we use are: Raspberry PI 2; Cobbler and Cobbler cable; DHT11 or DHT22 (They go as low as $4. CODE: dht11 = dht. And its accuracy reaches up to 2% RH and 0. This module can be used as a temperature and humidity acquisition for smart home or IOT project. Using Arduino Temperature Sensors. DHT11 temperature & humidity sensor, photoresistor. The DHT11 is a pre-calibrated digital output temperature and humidity sensor. Connecting the sensor to the Raspberry Pi. then use a DHT11 library Infact read this -How to Set Up the DHT11 Humidity Sensor on the Raspberry Pi Just leave out the LCD connec. This is a C library for Raspberry Pi. How to set up temperature and humidity sensor (DHT11) on raspberry Pi. It uses a capacitive humidity sensor, and a thermostat to measure the surrounding air temperature. It uses a single line for bidirectional serial communications. DH11 is a low-cost digital temperature and humidity sensor.
