In this tutorial we will see how to make a weather station with esp32 and electronic ink display. We will analyze the source code, as well as see the connections of the electronic components, finally test the project with its operation. The printed circuit board is included completely free of charge.<\/p>\n

FEATURES of the ESP32-T module<\/h4>\n
<\/p>\n
Connectivity<\/h3>\n
\n
The ESP32 module has all the\u00a0wiFi variants:<\/strong><\/p>\n
\n
802.11 b\/g\/n\/e\/i\/n<\/li>\n
Wi-Fi Direct (P2P), P2P Discovery, P2P Group Owner mode and P2P Power Management<\/li>\n<\/ul>\n
This new version includes low-power\u00a0Bluethoot<\/strong>\u00a0connectivity<\/p>\n
\n
Bluetooth v4.2 BR\/EDR and BLE<\/li>\n
BLE Beacon<\/li>\n<\/ul>\n
In addition, you can communicate using\u00a0SPI, I2C, UART, MAC Ethernet, Host SD protocols<\/strong><\/p>\n
Microcontroller features<\/h3>\n
\n
The\u00a0CPU<\/strong>\u00a0consists of a\u00a0Tensilica LX6 Model SoC<\/strong>\u00a0with the following features and memory<\/p>\n
\n
Dual 32-bit core with 160MHz speed<\/li>\n
448 kBytes ROM<\/li>\n
520kByteS SRAM<\/li>\n<\/ul>\n
Have\u00a048 Pins<\/strong><\/p>\n
\n
18 12-bit ADC<\/li>\n
2 8-bit DAC<\/li>\n
10 pin contact sensors<\/li>\n
16 PWM<\/li>\n
20 Digital inputs\/outputs<\/li>\n<\/ul>\n
Power and consumption modes<\/h3>\n
For proper operation of the ESP32 it is necessary to supply a voltage between 2.8V and 3.6V. The energy you consume depends on the mode of operation. It contains a mode,\u00a0the Ultra Low Power Solution (ULP),<\/strong>in which basic tasks (ADC, PSTN…) continue to be performed in Sleep mode.<\/p>\n
\n
TEMPERATURE and Humidity Sensor DHT11<\/h4>\n
$\"\"$ <\/a><\/p>\n
This module consists of a DHT11 digital humidity and temperature sensor and a resistance of 1 ko. The DHT11 uses an internal thermistor and capacitive humidity sensor to determine environmental conditions, an internal chip is responsible for converting readings to a serial digital signal.<\/p>\n
\n\n\n\n\n\n\n\n\n\n\n
Operating voltage<\/td>\n 3.3V to 5.5V<\/td>\n<\/tr>\n
Humidity measurement range<\/td>\n 20% to 90% RH<\/td>\n<\/tr>\n
Humidity measurement accuracy<\/td>\n \u00b1 5% RH<\/td>\n<\/tr>\n

Electronic ink display 4.3 Inch E-Paper 800\u00d7600<\/strong><\/p>\n<\/div>\n
$\"\"$ <\/a><\/div>\n
<\/p>\n
Overview<\/strong><\/p>\n
This is a serial interface E-Ink display module, 4.3 inches, 800 \u00d7 600 resolution, with built-in font libraries, ultra-low power consumption.<\/p>\n
You don’t have to know anything about e-Paper’s complex underlying details, or the specific algorithms for displaying graphics, texts, and images. All you need is the serial interface, and all that matters is your creativity.<\/p>\n
Features<\/strong><\/p>\n
\n
Easy to use, it displays any content through a serial interface, including geometric graphics, texts and images<\/li>\n
Embedded font libraries, supports Chinese 32-point, 48-point, and 64-dot GBK fonts and English fonts<\/li>\n
The built-in 128MB NandFlash allows source\/image data to be stored on an external TF card or on the internal NandFlash<\/li>\n
4-level gray display, resolution 800 \u00d7 600<\/li>\n
Adjustable serial interface baud rate, 115200 by default when turned on<\/li>\n
Powered from 3.3V to 5V, compatible with logical level.<\/li>\n
Ultra-low power consumption, resting current less than 5 mA<\/li>\n
Comes with host computer software, control it directly on your computer<\/li>\n<\/ul>\n
Applications<\/strong><\/p>\n
