Reviewing Dorji’s DSTH01 digital temperature and humidity sensor module
Raj did a review of Dorji’s DSTH01 digital temperature and humidity sensor module:
This entry was posted in kit biz, sensors and tagged DSTH01, review.
The DSTH01 module is smaller than 0.4″X0.4″ in dimension and operates at 2.1-3.6V power supply. The pull-up resistors for I2C lines are available on board. I tested this sensor module with Crowduino (an Arduino Duemilanove clone with Atmega328) using Jonas Bo Jalling’s Si7005 Arduino library, and worked like a charm. Crowduino has an on-board power select switch to chose the supply voltage for operation between 3.3V and 5.0V. I chose it to operate at 3.3V (although it should not matter too much as I2C lines are already pulled-up to 3.3V from the sensor module). Since the DSTH01 module interface pins are not 0.1″ standard, I soldered the pins onto a small general purpose prototyping board and made the pins accessible through a 0.1″ male header pins
