Logo Circuit Creations- Digital Temperature Controller & Switch Kit

The extensive capabilities of the microcontroller in this kit have been pre-programmed to provide temperature on-off control with digital set point.  This kit is a great building block for projects to monitor your computer fan air temperature, control fish or other tank temperatures, monitor your refrigerator, use in a gaming application, control a fan for cooling, control a heating element, create a temperature controlled switch, set off a freezing or overheating alarm, implement a room or equipment temperature thermostat…  Your imagination is the limit for what can be done with this kit.

Simple Digital Temperature Controller and Switch Kit Features

  • Typical 3C accuracy, no calibration required
  • LED indicator of temperature trip point
  • 7 switches to digitally select temperature set point in 0F or 0C, ranging from -10C to 100C
  • Small, 2.2” x 1.7”, double sided, 0.062" thick, Printed Circuit Board (PCB) with top side silk screening and mounting holes
  • Dedicated output is activated at temperature trip point and remains latched until reset
  • All microcontroller signals are accessible with through-hole pads at the edge of the PCB
  • Add your own circuits with surface mount and through-hole component prototyping section included on the PCB
  • Wide input voltage range (2.7V to 12V) with very low stand-by power, suitable for battery operation
  • Open collector output for connection to higher power circuits and relays
  • Switch selectable over or under temperature trip point

This kit consists of a Printed Circuit Board (PCB) and Electronic Components (Schematic, Instructions, Parts List are on our website: https://circuitcreations.com/manuals  ).  All kit contents are packaged in a resealable anti-static bag and shipped in a padded envelope.

Note: This is a kit and assembly is required.  You will need soldering tools and basic soldering skills.

Here's a video demonstration of the Digital Temperature Controller & Switch kit (after assembly).
