Temperature Controlled Box Arduino

The picture above shows the connections of the analog sensors.

Temperature controlled box arduino.

The temperature control lab is an application of feedback control with an arduino an led two heaters and two temperature sensors. Lm35 gives analog output proportional to the temperature which is given to arduino analog input a0. I m considering using arduino as a climate controller however the build would cost about as much as basic climate controllers. The heater power output is adjusted to maintain a desired temperature setpoint.

Climate control box arduino build would it be possible to use an arduino build to both control climate temp humidty lighting while also logging temp humidity. The 5v output of the arduino uno must be linked to all the 5v connections arrows. Thermal energy from the heater is transferred by conduction convection and radiation to the temperature sensor. The living room temperature is now controlled by the living room thermostat by opening or closing the electric valve in the floor heating.

Setting value is taken from button. We are using 16 2 lcd to display current temperature and set points. While on it provides 5 v to relay 2. Control the temperature of your aquarium or greenhousethe sensor ds18b20 measures the temperature of your aquarium or greenhouse.

The relay 1 is the heater on off. The display shows the current temperature and the status. Connect the components as shown in the schedule. The humidity control holes can be made by poking a pencil through the styrofoam thermocol box at the top.

Building it is fairly straightforward. I m new to the arduino land and small electronics in general and am looking for some help validation from you knowledgeable folks out there. Circuit is constructed using arduino uno and lm35 temperature sensor and other components. Learn how a pid controller for temperature works.

If you made lot of unnecessary holes or if humidity or temperature is escaping too fast you may cover some of the holes using electrical or duct tape. How to build it. Cooling or heating 25 c relay channel 1 active. Vdd comes from arduino 5 v pin vout goes to the a0 a1 a2 a3 analog pins of the arduino board gnd is common with the high power digital part of the circuit on the other hand the picture 9 below reveals how the two stage heater works.

The pcb has buttons i also make program to use 3 of them for function. Arduino temperature controller circuit. I m constructing a bbq smoker and plan to use the ardunio to control the temperature with two temperature probes as input meat and pit and a 1500w heating element.
