Hello, Hello, I am using a NTC 100k 3950 thermistor to measure the temperature of the hotend of 3D printer. I just wire the heater, thermistor, and Arduino UNO to test if the reading relatively correct. I reference the code from Adafruit written by Lady ada: Thermistor However, it seems doesn't work at high temperature (like 230-240), and I always get the temperature reading is -273.15 at high ...
Greetings every one I am currently working on a simple RTD Temperature sensing setup , so far i am following this article , i have built the exact same circuit , the only difference is that i am using 3 wire PT100 RTDs …
I am searching for a really accurate and quick temperature sensor that would cooperate with my Arduino UNO. It must be water proof (it will measure the temperature of a liquid). I need accuracy of +-0,1 degree Celsius, and scope of 0-150 degrees Celsius.
According to the datasheet, an RP2040 has an internal temperature sensor, measuring the temperature of the chip. How can one read this sensor of the Nano RP2040 using circuitpython?
Good morning, I am working on a project that uses the temperature sensor. It's set up with 3 LED lights that turn on when the temperature is 2, 4, and 6+ degrees above the baseline temp. However, I am having trouble setting the baseline. When I first open the serial monitor to see the temp in open air, picture 1 are the readings I was getting. So I set the baseline temp at 23 degrees. When I ...
Hello, does anyone know how to read ESP32-S2 built-in temperature sensor? There is an official documentation with and example available at: Temperature Sensor - ESP32-S2 - — ESP-IDF Programming Guide v5.2.1 documentation but Arduino does not find #include file driver/temperature_sensor.h
I see posts on occasion about using automotive sensors with the Arduino. I have tested a popular GM coolant sensor, part #12146312 with my Uno and tested it on the bench. This sensor mounts using 3/8 pipe and has a 2-wire connector. The datasheet is here and lists the mating connector: DELPHI COOLANT TEMPERATURE SENSOR PART NUMBER 12146312 I thought I'd share the info if anyone in the future ...
I'm trying to use an OPTA to manage an HVAC system with 6 temperature sensors (initial plan was PT1000) and 2 flow sensors output 4-20ma). unfortunately the opta analog expansion handle only 2 PT1000 sensor, and is a non sense buy 3 expansions. I evaluated the ds18d20 that I applied in the past to arduino, but discovered that input are only analog and did not handle this sensor (confirmed also ...
Hello, I'm trying to use a two wire RTD (Safety and Productivity Solutions | Honeywell) with an arduino uno to measure temperature. The rtd has a nominal resistance of 1000 ohms at 0 degrees, and 1100 ohms at 26 degrees. I've developed some code for it and have a wheatstone bridge type setup (similar to the one shown here: Resistance thermometer - Wikipedia). I'm using the uno's 5V output and ...
I have connected a KY-028 digital temperature sensor for measurement of body temperature . I have interfaced but I'm not getting proper output even though I adjusted with potentiometer values. it reads the environmental temperature but when I place my hand on thermistor my value is getting decreased. what should I do? how should I rectify this issue? I need this help. I have connected the LED ...
