SHT35 Humidity & Temperature sensor

Other Hardware Sensors

I want a library SHT35 Humidity & Temperature sensor. Please help me.

Look at the library for the SHT31-D from Adafruit. It might be close enough to get you started.

This example may also help. The 'D' version is digital output and the 'A' version is analogue. If you don't need the accuracy of the 35 then the 31 in breakout board form from Adafruit is a good choice.

I test module SHT35 by this code from adafruit but result :

SHT31 test
Failed to read temperature
Failed to read humidity

i connect arduino uno r3 with module SHT35

vcc(red) - 5v
gnd(black) - gnd
sda(yellow) - A4
scl(white) - A5

Please help me to understand. Thank you

Check the operating voltage of the SHT35 as it may be 3.3V. If so, you will need to power it from the 3.3V pin of the Uno and use a bidirectional level converter for the I2C signals. You may also want to run an I2C scanner to find out which address the module has assumed. If the address pin on the module is left floating then it should be pulled down with a low value resistor, 1K, or grounded. The fact that the code found the module at 0x44 says it's correct but do not leave the address pin floating.

If you've operated the module on the wrong voltage, it may already be damaged. The Adafruit breakout contains a voltage regulator and level converters. It's just a matter of how accurate you want your readings.

you are using the analog pin
SHT35 is digital
try to connect it on the digital pin of your uno
