Circuit Description of ESP8266 Temperature Logger using PIC16F887
Fig. 1 below gives details of the circuit layout of this project. The project includes microcontroller PIC16F887 MCU (IC4), ESP8266 Wi-Fi module, logic-level shifter, LM35 temperature sensor (IC3), 3.3V regulator LM1117-3.3 (IC2), 5V regulator 7805 (IC1) and 16×2 LCD module (LCD1) as the building blocks.
The entire circuit is powered using two power sources; 5V is required for PIC16F887, LCD and Logic-Level Shifter IC where ESP8266 module requires 3.3V. Since this ESP WiFi module intakes a regulated 3.3V altogether, you can replace IC2 with an adjustable voltage regulator, but be sure the voltage is precisely 3.3V.
The temperature sensor IC3 collects data and then forwards as input to IC4 through pin 2. The IC4 is responsible to transmit data to the Wifi module(ESP8266) via a logic level shifter. Finally, we can read the recorded temperature details on the screen of our gadgets; smartphone and laptops browsing through ThingSpeak website once the WiFi module executes data transmission process.
We establish the connection between the Wi-Fi modem of the user to ESP8266 Wi-Fi module and the temperature details are loaded onto the website of ThingSpeak, and it allows us to view the statics of temperature data on our devices through browser.
For visual interpretation of the project, LCD(pins D0-D7) is interfaced to IC4 (port B) which displays information about the circuit status and recorded data.
