The invention discloses a multifunctional remotely-controlled trolley for environment collection. A trolley body is driven by a four-wheel direct-current gear motor and three strings of 3.7-V lithium batteries are connected in series to provide power for the trolley body. Five sensors, a controller, a wireless module, and a liquid crystal display screen are arranged at the trolley body. The five sensors consist of a DS18B20 temperature sensor, a DHT11 digital temperature and humidity sensor as an environment humidity acquisition module, a BH1750FVI light intensity sensor, a gas concentration detection MQ-2 smoke sensor, and an HC-SR501 human body induction module. The controller includes a main single-chip microcomputer and an auxiliary single-chip microcomputer; the main single-chip microcomputer and the auxiliary single-chip microcomputer employ STC12c5a60s2 type ones. An STC12c5a60s2 chip, an nRF24L01 wireless module and a 12864LCD liquid crystal screen are arranged on the remote controller. According to the multifunctional remotely-controlled trolley provided by the invention, on the basis of the modularized-design structure, all functions are not affected mutually, so that the humanized and intelligent levels are high.
