QK145 firmware upgrade

Serial Temperature Interface Firmware Upgrade

Kit not included


Availability: In stock



Product Description


    The QK145UF is the new and improved firmware. This is not the orignal firmware and is copywrite QKits Ltd 2006. Behaves just as previous version but allows the selection of Celsius, Fahrenheit on the fly as well as data verification of the data returned from the sensor. An error in the data will be appended with a "!". The Fahrenheit conversion is accurate throughout the entire range, unlike the original firware that comes with the QK145.

    The QK145 with the upgraded firmware is a PC controlled 4 channel temperature meter (deg C or F) using the serial port, a PIC12C509 and supports up to 4 x DS18S20 sensors. (One DS18S20 sensor included) No external power required. We think that each DS18S20 may be located over 200 meters away from the motherboard and PC.

    This is an 8-pin micro-controller based circuit for temperature data logging via the serial port of any computer from between 1 and 4 remote digital temperature sensors, DS18S20 made by Dallas.


    Provides real-time data via the serial port, by interfacing with up to 4 DS18S20 Dallas temperature sensors. It has an accuracy of 0.5 degrees centigrade. You must choose either Fahrenheit or celcius based on a jumper. There is no external power required, because it gets its power from the serial port. The data stream is easily logged & processed. You can run each sensor over 200m distance from the board.

    We have not provided cables to connect between the kit and each remote sensor. But we do provide a harness and connector for easy connection of the cables to the PCB.
