Hey guys, I'm new to Arduino.i have a small doubt. Is it possible to interface this module with arduino. Its an air quality sensor module.

hi S31,
Welcome to AAC.
One option is to use a MAX232 RS232 TTL level converter between the sensor and the Arduino.
You could write a Software UART routine to 'listen' to the sensor, via the MAX232, leaving the hardware UART free for the PC comms.

Here is the data sheet for the sensor. It includes the protocol for communicating with it.:

One option is to use a MAX232 RS232 TTL level converter between the sensor and the Arduino.

The datasheet says:

I don't think a MAX232 will be required. Superficially it looks like it would be best to choose a 3.3V Arduino.

 

This will afford a bit of an overview using an Arduino UNO which uses 5.0 Volt logic or TTL logic of 5.0 volts. Your linked device reflects:

1. Working Voltage: 5V DC
2. Physical Interface: XH2.54-4P
3. Output Signal: UART (TTL)
4. All In One – Air Quality Monitoring Sensor Module

Reading the data sheet I am not sure what they are getting at with Interface Level verse Output Signal?

Hi,
This clip from Arduino.
RS232 devices use high voltages that are not compatible with an Arduino's TTL voltage levels and may damage an Arduino. You can use a device such as a MAX232 to convert between RS232 and TTL voltage levels.

If the TS connect the sensor to the Arduino Serial Port pins, he must have a level shifter,

Update:
There is so much contradictory information on the web, I am going to check the Board levels with a scope.

Added: from the official Arduino site
Serial communication on pins TX/RX uses TTL logic levels (5V or 3.3V depending on the board). Don't connect these pins directly to an RS232 serial port; they operate at +/- 12V and can damage your Arduino board.

Hi,
Do you have the arduino code that you have used for the ZPHS01B board? I have started using it to do little for a project and it would be very useful to have it.
