The invention discloses a temperature-and-humidity-adjustable vehicle type recognizer which can adapt to high-temperature, low-temperature and high-humidity environment. The temperature and humidity in the vehicle type recognizer can be reduced automatically to ensure the normal usage of a light curtain sensor. The temperature-and-humidity-adjustable vehicle type recognizer comprises a casing, the light curtain sensor, a cover plate, a fan, a temperature and humidity sensor, a power supply, a controller, a dual-piezoelectric-film sensor, a support rod, a base and two heaters; when the temperature in the casing is higher than a set maximum temperature, the fan is started to reduce the temperature; when the temperature in the casing is lower than a set minimum temperature, the heaters are started to increase the temperature; when the humidity in the casing is higher than a set maximum humidity, the heaters are started to reduce the humidity.
