Hardware Overview
How does it work?
Thermo 20 Click is based on the TSYS03, an ultra-compact digital temperature sensor with precise digital output and low power consumption from TE Connectivity. The TSYS03 is factory-calibrated and provides accurate temperature measurements through several I2C configurable addresses. Operating from a supply voltage between 2.4V and 5.5V and drawing just 5µA Thermo 20 Click board™ is well suited for battery-powered and automotive applications. With an extended operating range from -40°C to +125°C, the TSYS03 provides digital temperature measurements that offer an accuracy of ±0.5°C when operating at ambient temperatures between 0°C and 60°C. The TSYS03 consists of a semiconductor
diode as a measuring element, which was integrated into an ASIC. The temperature is obtained from the voltage that drops across the diode and through an A/D converter with a 16-bit resolution. The output is obtained as a digital value via a configurable I2C interface. The TSYS03 impresses with its high accuracy, current consumption lower than 5 µA, and low self-heating of max. 0.1 °C. Thermo 20 Click communicates with MCU using the standard I2C 2-Wire interface with a maximum clock frequency of 1MHz. The standard I2C address is 0x40, but the sensor can also react to a second, alternative I2C address. It is possible to do one-time subsequent writing of an alternative static I2C address.
This leads to a wrong memory CRC, but the sensor is still functional. It is also possible to write an alternative I2C address to the sensor during operation. This address is temporary and is overwritten during a software reset or a hardware restart function. This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.
Features overview
Development board
PIC32MZ Clicker is a compact starter development board that brings the flexibility of add-on Click boards™ to your favorite microcontroller, making it a perfect starter kit for implementing your ideas. It comes with an onboard 32-bit PIC32MZ microcontroller with FPU from Microchip, a USB connector, LED indicators, buttons, a mikroProg connector, and a header for interfacing with external electronics. Thanks to its compact design with clear and easy-recognizable silkscreen markings, it provides a fluid and immersive working experience, allowing access anywhere and under
any circumstances. Each part of the PIC32MZ Clicker development kit contains the components necessary for the most efficient operation of the same board. In addition to the possibility of choosing the PIC32MZ Clicker programming method, using USB HID mikroBootloader, or through an external mikroProg connector for PIC, dsPIC, or PIC32 programmer, the Clicker board also includes a clean and regulated power supply module for the development kit. The USB Micro-B connection can provide up to 500mA of current, which is more than enough to operate all onboard
and additional modules. All communication methods that mikroBUS™ itself supports are on this board, including the well-established mikroBUS™ socket, reset button, and several buttons and LED indicators. PIC32MZ Clicker is an integral part of the Mikroe ecosystem, allowing you to create a new application in minutes. Natively supported by Mikroe software tools, it covers many aspects of prototyping thanks to a considerable number of different Click boards™ (over a thousand boards), the number of which is growing every day.

* # Description
* This example showcases the ability of Thermo 20 Click board to
* read it's serial number. It can read themperature and measure from -40degC to
* 120degC.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initialization communication modules(I2C, UART). Resets device and read Serial Number.
*
* ## Application Task
* In span of ~ 1000ms it sends command for adc conversion of temperature, reads ADC value,
* and calculates temperature in degrees C.
*
* @note For this driver to work on 18bit PIC MCU-s you need to additionally pull up communication lines.
