Our syntax highlighter tends to mess up the code so I will include the Xojo modules that act as device drivers as links here. Interfacing with this sensor is complex, and it felt as if I was writing a device driver. Then it starts sending the data where every bit starts with 50 microsecond LOW, then the time length of the HIGH determines if its 0 or 1.ĭHT11 and DHT22 use the bits a little bit differently see the Xojo modules for the code of that. The sensor will pull down the pin to low for 80 ms, and then back up to high for 80 ms before sending the actual data. Then pin is put to high for 40 microseconds. In my example then I have it connected as follows:ĭata pin is pulled down to low for at least 10ms to send start signal to the sensor. Make sure your Raspberry PI is not powered on when you do the connections. Xojo uses a proprietary object-oriented language.

The far nicer DHT22 sensor costs about $3.45 a piece. DHT11 or DHT22 (They go as low as $4.91 for 5 pieces ($0.98 a piece) on Aliexpress where I got this one.Incorrect wiring can result in damaged sensor or damaged Raspberry PI. We do not take any responsibility for possible errors in the guide or errors that you might do wiring it up. Note that many types of those sensors exist, I had a 3 pin type, they also exist with 4 pins. Visual Basic (VB) är ett programspråk i BASIC-familjen som är utvecklat av Microsoft. The DHT22 sensor is far superior over the DHT11, it gives far better and more correct readings and handles negative temperature as well. The DHT22 has higher resolution but similar protocol.
#XOJO MSGBOX DRIVER#
Oct 2015, greatly improving the DHT11 device driver code and added DHT22 device driver code and wiring pictures for the DHT22) Xojo (Real Studio, REALbasic) MsgBox avec OUI/NON et non pas YES/NO MsgBox avec OUI/NON et non pas YES/NO. This sensor reads both the humidity and temperature. In this example we are going to connect to DHT11 and or DHT22 humidity & temperature sensor.
