DHT12 Sensor Interfacing with Linkit Smart 7688 Duo using Python/Arduino

Bikash Narayan Panda

I got the Linkit 7688 Duo couple of years back but was not able to work on it apart from getting started and programming the onboard Atmega(w/ Arduino Bootloader) using Arduino IDE video. But recently I thought of checking out the python programming aspect of it, as the MPU runs an OpenWRT based lightweight OS over which we can run any programming language as long as the limited resources available on the board are sufficient. The board comes with one MPU (MT7688) and one MCU(Atmega32U4) I am working on a…

DHT12

This video around raspberry pi showing how to interface DHT12 humidity and temperature sensor with raspberry pi by using JAVA nad Pi4j. DHT12 its a temperature sensor with a 1-Wire and I2C interface to connect with external controllers and having 1-Wire interface makes it compatible with the older DHT11 sensor but with a higher accuracy. For this tutorial, we are going to use the I2C interface of the sensor and to interact with it, we will be using JAVA. One issue with the DHT12 I2C interface is that the device…

DHT11 | Interface using JAVA | Raspberry Pi

Bikash Narayan Panda

The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old. Source : Adafruit…
