PCC1030B: Measurement (4xDHT22) and display on PC temperature and humidity (%RH) - FreeHex!
After updating the offered Arduino code and PC Application, it is possible to read and show on PC 4 temperatures and RH(%)
For Arduino boards:: NANO -- UNO -- MEGA
Arduino pins are used: see connections - (used Sensor(s)=DHT22 - Lnk1 - Lnk2 )
 
Electrical note: (Recommendation:Use the following accessories for testing as well as for later use: Lnk1 - Lnk2 )
Used pins are connected to 5V via resistor(s) 3K3-4K7 (if the sensor does not have a built-in resistor)
Only power from the computer's USB port can be used (An external power source is not required).
 
Download FreeHEX codes below, unpack and upload to the proper Arduino board (Use a free net tool for example XLoader)
1. uc ATmega328-16MHz-5V (NANO,UNO...): PCC1030B-M328
2. uc AtMega2560 (Mega(ATMEGA2560).....): PCC1030B-M2560
 
You can test the uploaded code using some free serial communication software such as Termite
Description of program commands
AT command (ASCII characters) - 9600 Baud ,8 Data bits,None Parity,1 Stop Bit - AT commands must be uppercase, lowercase invalid
AT - attention command (returns OK)
AT+INF - software code info (returns ucAppName)
AT+RV1A - Reading measured value (sensor=1 value=A (temp. C)) (one decimal digit form))
AT+RV1B - Reading measured value (sensor=1 value=B (RH%)) (one decimal digit form))
...... for sensor2 and sensor3.....
AT+RV4A - Reading measured value (sensor=4 value=A (temp. C)) (one decimal digit form))
AT+RV4B - Reading measured value (sensor=4 value=B (RH%)) (one decimal digit form))
 
ArduinoIDE source code (avaliable): see ProjCode
 
PC Application(s):
PC Application(s) (for WINDOWS): In order for the offered PC applications to work, it is necessary to download and install (only first time): VB6RunTimePlus2.2
Download the PC application, unpack and start (allow windows to start applications - how) enter the COM port number where the Arduino is connected and use that.
PcApp: PCC1030B-PcApp1try - Time limited version (2h - then need restart) for try! For no-limit version see ProjCode
