The humble DS18B20 is a go-to for us because of the multi-drop & long cable run aspects of the one wire bus. But we needed to improve on the factory accuracy of ±0.5°C and I think I finally have a process that delivers better than ±0.1°C from them: In this exercise, we're going to connect a Dallas DS18B20 temperature sensor to a breadboard, and read the temperature through the Raspberry Pi's GPIO pins. The DS18B20 has a 1-Wire interface, which means that one of its leads is used for serial communications. The other two leads need to be connected to 3.3V and 0V. Temperature Graph on a PCD8544 display, with DS18B20 temperature sensor. Using the Nokia 5110 display and the DS18B20 temperature sensor to make a simple temperature graph
The TMP35/TMP36/TMP37 are low voltage, precision centi- grade temperature sensors. They provide a voltage output that is linearly proportional to the Celsius (centigrade) temperature. The TMP35/ TMP36/TMP37 do not require any external calibration to provide typical accuracies of ±1°C at +25°C and ±2°C over the −40°C to +125°C temperature range. BeagleBone and DS18B20 Temp Sensor After deciding to switch over the the BeagleBone Black, we have been reconsidering using an Arduino to measure environmental variables. Using the numerous I/O pins on the BBB is not only easier, but more efficient in size and speed. By using a ESP8266 and 2x DS18B20 temperature sensors you can measure the temperature of the incoming & outgoing pipes of your central gas heater ('CV-ketel' in Dutch). This is conventient when improving efficiency of your installation.

Compare DS18B20+PAR price and availability by authorized and independent electronic component distributors. I want to build a thermistor temp sensor using arduino (as in above circuit) but then need to convert measured temperature in degrees centigrade to air flow in meters per second, and be able to display on screen, and record this via computer. I purchased the Photon maker kit and am attempting to use the DS18B20 temperature sensor that comes with the kit. (I’m kind of new to the photon but did get another sensor to work so am not a total newb.) Debugging indicates that the photon isn’t detecting the presence of the DS18B20 and is returning a temp of -127.0.

npm install node-red-contrib-sensor-ds18b20. Node-RED node for working with DS18B20 sensors, inspired in this library, but modified to behave slightly different with some extra functionalities. It is compatible only with RaspberryPi hardware and it only reads the temperature values from sensors. I have a question, no idea if this is obvious or it is a complex one. I have to setup a temperature body measurement sensor, that will be based on the high precision with memory IC DS1624 (see attached datasheet). The question is almost simple to explain: I need to find the way to convert this IC in a sensor.
