Initialize Sensor always fails

[Harithmetic1]

Good day, I have been looking for a library that works well with my ASAIR DHT20 sensor for a while now, and so far, your library is the only promising thing I have seen to date. However, whenever I run the example code (getData), it always prints out "Initialise sensor failed" to the serial monitor.

When I try to override it, by negating the while loop condition i.e while(!dht20.begin()) instead of while(dht20.begin()). I get a constant reading of 150.03C and 100% RH on my Serial monitor.

I have followed the connection on the ASAIR data sheet properly and installed this library on my Arduino IDE. Are there any reasons why this problem persists, and how can I get the correct readings from my sensor?

Here is a picture of my code for the first instance

I tried this lib, it works fine.

If begin fails, the sensor may be faulty. You can try to find the i2c address of the dht20 through some programs that scan the i2c address. If not, please replace a new module; If so, you can add a print to the begin function to see what the read data is. The information you have provided so far is not enough for us to find the problem, because the library worked well when we tested it.
