K-Type Thermocouple with MAX6675 Amplifier. A K-type thermocouple is a type of temperature sensor with a wide measurement range like −200 to 1260ºC (−326 to 2300ºF).

Apr 30, 2019 · In this list of Arduino sensors we’ll explain what each one is used for and some quick links to where you can purchase them. Although modules are not expressly sensors we’re including them in the list here along with the sensors. Modules could be LCD character displays, LED dots displays, transistor modules, and the like.

Nov 30, 2018 · In this tutorial we will be interfacing a LDR with Arduino Uno. Arduino Uno has a set of Analog input pins which can are used to take analog input signals from a sensor. Remember there are two types of signals: 1. Digital Signals : These signals have only two values i.e. 1 or 0 (on or off). 2. Analog Signals : These signals have values in a range.

Throughout this tutorial, I'll take you through how to assemble the circuit, sensor calibration, code, and test your prototype. If you're new to this or simply need a nice little project to tinker with, I hope this tutorial assists you in getting started. Let's go! I have added a photograph and file of the Fritzing diagram for reference.
