The invention discloses an agricultural Internet of things monitoring terminal based on MSP430F169. The terminal comprises a MSP430F169 microcontroller. The MSP430F169 microcontroller is connected to a temperature and humidity sensor, an illumination sensor, a CO2 concentration sensor, a clock chip, a 433Mhz wireless radio frequency module and an actuating mechanism driving module respectively. The CO2 concentration sensor adopts TGS4160. The TGS4160 is connected to the MSP430F169 microcontroller through an AM-4 detection module. A model of the temperature and humidity sensor is SHT11. A model of the illumination sensor is BH1750. The actuating mechanism driving module comprises a ULN2003 chip. In the system, the MSP430F169 is served as a master control unit; through sensor detection, digital signals of a temperature, a humidity, illumination, CO2 concentration, time and the like are collected; through the 433Mhz wireless radio frequency module, collected information is transmitted to a monitoring host; and s
