Thanks for your reply.It's no change when i restart device (power off and power on) or press reset button after upload success and show me 'Hard resetting via RTS pin'; But it's normal when I use example TFT_Touch_Shield_V2 and has not 'Hard resetting via RTS pin' tips after upload, my screen show example text normally.
Summary. The DHT22 sensor is a really nice sensor to measure temperature and humidity that can be used with the WeMos D1 mini. Although there is some complication as the standard DHT22 library cannot be used there is a library designed for the ESP8266 chipset such as the WeMos D1 mini. For a full review of the DHT22 have a read of my previous post.

Wemos D1 mini pro with DHT22 temperature & humidity sensor Adafruit Huzzah Feather with I2C display, multiple 1-wire temperature sensors, and light/lux sensor, all data presented on display Installation of ESPEasy firmware uses the Arduino IDE.
The Wemos D1 Mini is a great board to develop WiFi-based IoT Projects. It uses the popular ESP8266 Module for its IoT operations. Can be easily programmed through USB and requires no additional programmer.
Wemos mini bmp180 sensor example. This bmp180 from Bosch is the best low-cost sensing solution for measuring barometric pressure and temperature. The sensor is soldered onto a PCB with a 3.3V regulator, I2C level shifter and pull-up resistors on the I2C pins. The BMP180 replaces the BMP085.
