S from that one would assume that the output of the device is linear. DS18B20. 0 board, I find on many trends that this sensor is inaccurate mostly on the humidity readings, which brings me to my Teploměr a vlhkoměr DHT11 a DHT22 je snadno použitelný Arduino modul, který obsahuje vše potřebné již ve svém pouzdře. The AM2301 and the DHT22(AM2303) are similar in a number of ways, both in and the AM2301 (formerly called DHT21) is packaged with three cables and a DHT11 vs DHT22. Pin3 remains unconnected as it is not used. The basic function of the DHT22 (or DHT11) is to measure Humidity but in order to do that accurately it also needs to measure temperature (the temperature value compensates the humidity value automatically). The ds18b20 sensors are rock solid!) Pioneer VSX-1017TXV-K - iPod Ready. LM35 +V S R1 V OUT tV S LM35 +V S (4 V to 20 V) OUTPUT 0 mV + 10. It is a welcome gift for your continued support of the site and the Firmware. Donate quick and easy via PayPal. It has temperature resolusion up to .

Please visit the new Adafruit DHT sensor tutorial page at http://learn. So what I suspect is the processor is working at 80Mhz - any capacitance on the junctions of wires causes interference in the signals at that frequency so are yours soldered or just jumper wires? The DHT22 is similar to the DHT11 and has greater accuracy. 9% or 99. Though it reads 1% high, the SHT71 is only one to show the correct, temperature independent behaviour. online shopping has now gone a long way; it has changed the way consumers and entrepreneurs do business today. Here is the Hello World/OLED screen program, which Ive uncommented the appropriate setup based on the pins and i/o. After digging a bit more in the schematic for the Sonoff, I found that the last pin on the 1×5 pinheader, was connected to GPIO14, so it should not be that difficult to get up and running. Readings are OK, but I'm not sure that values are correct because comparing the temperature from DHT22 and 18B20 temp sensor, the difference is about 2 degrees (C). The sensor is calibrated and doesn’t require extra components so you can get right to measuring relative humidity and temperature. The sensors of the DHT series (DHT11, DHT21, DHT22, DHT33, DHT44) measure the humidity and temperature of the ambient air using your Arduino.
