Arduino Pid Temperature Controller Dht22

Control the temperature of your aquarium or greenhousethe sensor ds18b20 measures the temperature of your aquarium or greenhouse.

Arduino pid temperature controller dht22.

In very simple terms the temperature controller takes readings of the current state of the system and uses that data to determine whether to keep the heating element on. Temperature profile to process the vegetables properly. Download and install libraries required to support the devices we are using. My pid controller library on github is here.

How to connect a temperature humidity sensor such as the dht22 to an arduino. I am merely showing an arduino implementation. The farmer s canning application required executing a specific time vs. What i want is the aluminum block below to have let s say exactly 100 degrees.

For these reasons i decided to build an arduino pid temperature control unit. I ll control the real temperature using a k type thermocouple. The dht 22 is a sensor which measures relative humidity and temperature sensor and provides a calibrated digital output. After the interfacing of the arduino with dht11 rht01 sensor let s see how to connect the arduino with dht22 am2302 rht03 digital humidity and temperature sensor.

To read the data i ll use the max66 75 breakout module and control the pid algorithm with and arduino. It is an inexpensive sensor that is almost similar to the dht11 but measures temperature and humidity with higher accuracy and wider range. Relay channel 1 active. Refer to figure 1.

Initialize timer1 for 1 second interrupt initialize dht temperature humidity sensor data. The thermal control system is composed of the pid controller solid state relay ssr and 1 500w hotplate. The display shows the current temperature and the status.

I won t get into the details of the equation or the coefficients in this post. What s up my friends welcome back.
