With the features of quick build and convenient deployment,WSN can realize large scaleand automated real-time information collection.Use zigbee as the basic teechnology to design a kind of wireless hydrogen sulfide acquisition instrument.This instrument can not only collect temperature and humidity data from the spot,but also can sound the hydrogen sulfide concentration alarm while beyond its limit and so on.The device can improve the management of the production and provide the field staffs with reliable information to reduce and avoid the occurrence of hydrogen sulfide poisoning.
