Digital Thermometer Design

Microchip’s products suited for digital thermometer and sensing applications

Image of Microchip’s Digital Thermometer DesignMicrochip has a wide variety of products for medical applications including digital thermometers. Thermometers have been around for some time in traditional medical settings, but now digital temperature measurement devices can be found in many new and exciting places. For example, the ability to measure temperature is now being integrated into many consumer products such as connected fitness and medical activity trackers. Microchip’s connected thermometer board demonstrates the implementation of a Bluetooth®-connected digital thermometer using Microchip’s PIC16F1519 MCU and RN42 Bluetooth Module. The PIC16F1519 MCU is an eXtreme Low Power (XLP), cost-effective 8-bit microcontroller with an integrated capacitive touch sensing module. Connectivity is demonstrated on this board by the use of Microchip’s fully qualified RN42 Bluetooth 2.1 + EDR Module. This demo design can also be easily implemented using any of Microchip’s Bluetooth Low Energy or Wi-Fi® connectivity modules.
