Project Description:
********************
You might have watched my videos on DS18b20 one-wire digital temperature sensor, BMP180 Sensor which is capable of measuring the temperature, pressure, and Altitude, DHT11 sensor which is one of the most commonly used sensors and is capable of measuring the Temperature and Humidity, and my favorite one the MAX6675 K-type Thermocouple Temperature Sensor which I will be using today. I have already used all of these sensors in my previous projects based on the Arduino, Raspberry Pi, ESP32, ESP8266, STM32, etc. I will add links to all the related videos in the description.

The BMP180 and DHT11 sensors are good for monitoring the ambient temperatures and are used in places where surface contact is not needed between the sensor and the objects. The temperature range of the BMP180 Sensor is -40 to +85 Celsius while the temperature range of the DHT11 Temperature and Humidity sensor is 0 to +50 Celsius.

Now, the DS18b20 temperature sensor and the MAX6675 K-type thermocouple Temperature sensor; both are good for surface contact-based temperature monitoring. The temperature range of the DS18b20 is -55 to +125 Celsius while the temperature range of the MAX6675 K-type thermocouple is 0 to +1024 Celsius.

There is no doubt, the DS18b20 is an amazing temperature sensor, but due to its very limited temperature range, it just can’t be used in areas where you need to monitor high temperatures. DS18b20 has its own uses, personally, I have been using it with Arduino, STM32, Raspberry Pi, and IoT-supported controller boards like ESP32 and Nodemcu ESP8266 WiFi Modules. But, when it comes to the MAX6675 amplifier and the K-type thermocouple Temperature sensor, it’s just at another level, its ability to measure high temperatures makes it ideal for industrial applications.

In today’s episode, you will learn how to make Raspberry Pi Pico and MAX6675 K-type thermocouple-based Industrial Temperature Monitoring System.

very nice, it took me a few minutes to set this up

Excellent video, as usual. Great overview of the different sensors. I myself like the DS very much. It's acurate and cheap and it's range is perfect for me. Another advantage is de form factor. The stainless steel housing makes it easy to submerge into liquids.

Is ot possible to use multiple max6675 in raspberry pi pico? Actually in my system i need 4 sensor

[happymatekenya]

A very good video bro. If I may ask what simulator did you use before connecting everything up? I am having challenges on what simulator is best for pico W in regard to a temperature measurememt application like this.

Interested in doing something similar in C#, is the Max library open source so that I could port it?

[neonicblader]

Hi question, would you know of a flat surface temperature sensor that I could lay on something using the raspberry pi? Otherwise great job!

[ManiRNaidu]

Hii sir, can we able implement it in Raspberry pi 4 with same code

[TheJavaSync]

Pls, add PID code for better controlling temp 🙏

[BdyPhrk]

How to convert the library to circuit python?

[bhaskarpujagolla]

Great Job! I have one more requirement for the same project that is i want to connect mini printer which can print temperature, time and time, and the option for selecting printing interval.
Is this possible ? can you help me build this project .?

[comrastr]

Отличная работа, хочу повторить ваш проект, но на три датчика. Сделайте код , заранее спасибо!

I'm gonna learn everything on here...then I can basically do everything I'd wanna do at home right?

After documenting all your videos, I just need to learn about signal hijacking so that I can macguyver anyhting and hijack it's signal for automation purposes...I also need to learn how to have two components-value's be dependant on the other in the python script(also learn python), like I tell the thing to switch of AC-power to the lights if the temperature goes too high or to switch on a fan and balance all three-"components?"---see!? -"components" I dont even know the terminology..

I need to learn

But what book has all of that info? circuit analysis? or is that merely step 1? then what book comes after circuit analysis? I've don basic programming so python will come with time but how do u learn this electronic- BS, where is the

Estou tentando portar o código Micropython pra Esp32 porém não consigo mudar a pinagem no codigo. Alguma ajuda.
