- Full Video Course on How to build a 4 Channel LM35 amplifier board for Arduino using Kicad 6.0
We will learn to design and build an 4 channel LM35 temperature sensor chip Signal conditioner amplifier circuit based on the popular opamp LM324 using Kicad 6.0.The board can be used to monitor temperature from 4 different sources at the same time and can be used for building your own data acquisition system.
- The board consists of 4 analog channels for connecting the outputs of the LM35 chip and 4 output channels that gives the amplified output of the LM35 chip in the range of 0-5V, the Gain of all 4 channels is around 3.7.
- The board also has 4 amplified outputs that gives the amplified voltage in the range from 0-3V ,making it easier to interface LM35 to 3V tolerant microcontrollers like MSP430,STM32
- The board can also be used as a general purpose amplifier board that you can use to interface with other analog sensors and works with both 5V and 3.3 tolerant microcontrollers.
- The board is designed with Kicad 6.0 and the video tutorial teaches you how to design a circuit board from schematics to PCB with KICAD 6.0 EDA.
- All the components used in the circuit are through hole components which helps the user to build the circuit in true DIY fashion and learn valuable soldering skills.
- You can watch the full video of how to build the 4 channel lm35 amplifier on Youtube.
