To find out more about how to control text on an LCD with C, check out How to Setup an LCD on the Raspberry Pi and Program it With C. Lcd = lcdInit (2, 16, 4, LCD_RS, LCD_E, LCD_D4, LCD_D5, LCD_D6, LCD_D7, 0, 0, 0, 0) įor temperature in Celsius, un-comment line 72 where it says lcdPrintf(lcd, "Temp: %d.0 C", dht11_dat), then comment out line 73. LcdPrintf(lcd, "Temp: %.1f F", f) //Comment out for Celsius lcdPrintf(lcd, "Temp: %d.0 C", dht11_dat) //Uncomment for Celsius This C program will output the DHT11 readings to an LCD display: #include Printf( "Raspberry Pi wiringPi DHT11 Temperature test program\n" ) The following C program will output the humidity and temperature (in ☌ and ☏) readings to an SSH terminal: #include ĭht11_dat = dht11_dat = dht11_dat = dht11_dat = dht11_dat = 0 Gcc -o example example.c -lwiringPi -lwiringPiDevĬhange example and example.c to the file name you want to use. The examples below are stand-alone C programs, which will need to be saved to a file with a “.c” extension, then complied by entering this at the command prompt: If you don’t have WiringPi installed already, follow this link for instructions on how to install WiringPi. We’ll be using WiringPi to program the DHT11 in C. How to Write and Run a C Program on the Raspberry Pi.
How to Write and Run a Python Program on the Raspberry Pi.If you’re not familiar with writing and running programs in Python or C on the Raspberry Pi, check out one of these tutorials: I’ll explain how to use both C and Python to get temperature and humidity from the DHT11, so you’ll be able to incorporate the DHT11 into pretty much any existing RPi project. The resistor is a 10K Ohm pull up resistor connected between the Vcc and signal lines. An IC on the back of the module converts the resistance measurements from the thermistor and humidity sensor into digital temperature (in ☌) and relative humidity measurements. So instead of repeating all of that here, check out How to Set Up the DHT11 Humidity Sensor on an Arduino, then come back for the specifics on setting it up on the Raspberry Pi.īut just to quickly summarize… The DHT11 has a surface mounted NTC thermistor and a resistive humidity sensor. We have another tutorial on the DHT11 for the Arduino that goes into detail on relative humidity and how the DHT11 measures it. Then I’ll give you some example programs for programming it with either C or Python. In this tutorial, I’ll show you how to connect the DHT11 to the Raspberry Pi and output the humidity and temperature readings to an SSH terminal or to an LCD. Programming the DHT11 and connecting it to a Raspberry Pi is pretty simple too.
