CC3200: Linking library for MQ-135 (air quality sensors), DHT22 (temp+humidity sensor) and luminosity sensor

Part Number: CC3200
Other Parts Discussed in Thread: ENERGIA, TMP006

How can link MQ-135 (air quality sensors), DHT22 (temp+humidity sensor) and luminosity sensor to cc3200. Is there any inbuilt libraries for them, if yes, can you please help me with that.

Thanks.

    Hi,

    Welcome at forum.

    There is no official support for this 3rd party sensor (MQ-135, DHT22) by TI. You need implement this sensors by yourself by avaialble datasheets and libraries for other platforms available of Internet. Maybe you you can try port Arduino libraries for Energia ( http://energia.nu/ ).

    CC3200 LaunchPad contains two sensors itself (temperature sensor TMP006, accelerometer BMA222).

    But about MQ-135 I want to warn you. It looks that this sensor have voltage output up to 5V. Although the CC3200 has embedded ADC, input voltage is limited to 1.8V. Higher voltage can damage CC3200. From this reason you cannot connect directly MQ-135 to CC3200. Digital pins of CC3200 are also not 5V tolerant. Application note for ADC you find here - processors.wiki.ti.com/.../CC3200_ADC_Appnote

    Thanks!

    So, can you please suggest humidity and air quality sensors which can directly be connected to CC3200. 

    Also please suggest levelers so that we can give input from Arduino to CC3200
