It appears from the photos that you are using a DHT11 on a breakout board. The pin connections on these boards are different from the raw DHT11 on its own.
You appear to have 3.3v (black wire) connected to the Data pin, GND (blue wire) connected to the Vcc pin, and D3 (green wire) connected to GND.
You’re also trying to read the sensor too frequently, and you are getting muddled-up with GPIOs and Blynk Virtual pins.
It would also be a good idea if you read this:
and an even better idea if you threw the crappy DHT11 in the bin and bought something like the BME280 instead.
