Demoboard with EA uniTFTs028-ATC: EA DEMOPACK-CLIMA CO2 measurement

2 left in stock
For quantity 10+

EA DEMOPACK-CLIMA demo application for EA uniTFTs028-ATC display with application PCB for CO2 measurement, temperature measurement and humidity measurement via I²C.

The Si7020-A20 sensor is used for the temperature and humidity measurement and the CSS811B-JOPD500 gas sensor for CO2 measurement.

This applications shows communication between the EA uniTFTs028 smart display, the sensors and the Real-Time-Clock (RTC) the I²C.

The Real-Time-Clock is battery buffered.  Demoboard has a reset switch and test points for GND and VDD.

The display included with the EA DEMOPACK is the EA uniTFTs028-ATC 2.8" IPS TFT smart display with PCAP touch-screen and powerful graphics functions and memory. The series of uniTFT(s) displays can be programmed as stand-alone HMI controller with inputs and outputs. Display interface is USB (5V), serial, I²C and SPI (3.3V). A level converter is required for RS-232 (+/-12V). For examples using a level converter for RS-232 and RS-485 communication check out the EA DEMOPACK-CONNI.

Ease move objects, change and display measured values, automatically highlight parameters, fade in and out controls gently. Program and create control screens with the Windows uniTFTDesigner software.

Should the project require a smaller or larger display then do not worry, the uniTFTs displays are available from size 2.0", 2.8", 3.5" and 4.3". The larger and more powerful uniTFT displays are available in size 5.0", 7.0" and 10.1"
