DHT11 Humidity and Temperature Sensor

What we have to do to read a DHT11 sensor is: 1) Send request 2) Read response 3) Read each data segment and save it to a buffer 4) Sum the segments and check if the result is the same as CheckSum If the CheckSum is correct, the values are correct so we can use them. If CheckSum is wrong we discard the packet. To read the data bits can use a counter and start count uSeconds of High level. For ...
