The utility model belongs to the technical field of deep sea detection technology and specifically relates to a platform monitor sensor is used in oil gas development of multivariable ocean based on thing networking. It includes master controller, clock module, data memory, wireless transmitter, acceleration sensor, angular transducer and temperature and humidity sensor, acceleration sensor is connected to the master controller through filter module and the AD conversion module who sets gradually, temperature and humidity sensor and angular transducer lug connection master controller, and the sampling time of master controller reading clock module, the master controller is write in received data signal and the sampling time who reads simultaneously into among the filter module 0 and is carried to outside filter module 2 through filter module 1 simultaneously. The utility model discloses the master controller is as an organic whole with sensor collection such as acceleration, humiture, inclinations, realizes the synchronous sampling, processing, storage, output of corresponding data etc. And then is favorable to improving data acquisition's accuracy nature, data acquisition's variety, can satisfy the service conditions of the long -term monitoring of platform.
