Abstract

A digital humiture controller comprises a digital temperature sensor, a digital humidity sensor, a microprocessor and a display screen, wherein the digital temperature sensor and the digital humidity sensor are in direct connection with the input terminal of the microprocessor, and the output terminal of the microprocessor is connected with the display screen. The utility model has high measuring precision and accuracy and good stability and is capable of complete exchange, and the sensor has super-long signal transmission distance.

Description

The digital Temperature and Humidity controller

Technical field

The utility model relates to a kind of temperature and humidity control device.

Background technology

Temperature and humidity control device is a purposes control instrument very widely.The technology that temperature and humidity controller adopts at present mostly is to use the humiture information of temperature sensor and humidity sensor perception environment respectively, the voltage of being changed that becomes certain funtcional relationship with temperature, humidity or the simulating signal of electric current are sent analog to digital conversion, and then convert digital code to and show.Like this, often precision and accuracy are difficult for carrying out.

The temperature and humidity controller of prior art also needs extra components and parts forming circuit to carry out signal Processing, and sensor can not conveniently exchange; On using, be subjected to multiple restriction.

Summary of the invention

The utility model purpose is that proposition a kind of high-precision digital temperature and humidity controller, especially precision height, long-time stability are good, the digital Temperature and Humidity controller that sensor can conveniently exchange.

The technical solution of the utility model is: the digital Temperature and Humidity controller, constitute by digital temperature sensor, digital humidity sensor, microprocessor and display screen, digital temperature sensor, digital humidity sensor directly connect the input end of microprocessor, the output termination display screen of microprocessor.

Other output terminal of microprocessor also is provided with driving circuit, and driving circuit can be an on-off circuit, is used for air-flow cooling devices such as control heater or fan.

Digital output sensors directly connects microprocessor, and its long-time stability are good, and the temperature and humidity sensor can conveniently exchange, and adopts charactron and driving circuit on the display screen, and effect is better.

The beneficial effects of the utility model are: described digital Temperature and Humidity controller measuring accuracy and accuracy are all higher, and good stability is owing to can exchange fully, so safeguard and keep in repair very convenient.Comprise and to adopt two types of metal shell and plastic casings, select for use the high components and parts of interference free performance can satisfy different needs in the internal circuit, can also in highfield, strong magnetic field circumstance, the moving of metal shell.Sensor is all through accurate calibration, additionally components and parts; Sensor has the signal transmission distance of overlength, super low energy consumption, and 4 pins are installed.

Embodiment

The digital Temperature and Humidity controller is made of digital temperature-humidity sensor (AM2303, AM2302, DHT11), microprocessor (ATMEGA8, ATMEGA16, AT89S52) and display screen, digital temperature-humidity sensor, directly connect the input end of microprocessor, the output termination display screen of microprocessor.

The output terminal of microprocessor also is provided with driving circuit, and driving circuit can be an on-off circuit, is used for air-flow cooling devices such as control heater or fan.

According to required environmental baseline the humiture parameter is set.Controller is measured humiture in real time by the ambient temperature and humidity information of digital temperature-humidity sensor perception, measured humiture numerical value is shown by panel after treatment, compare judgement with the parameter of setting simultaneously, control heater and fan are in rational state, guarantee that ambient temperature and humidity is in the scope of setup parameter.

If the controller dead electricity, perhaps well heater, fan, sensor abnormality then provide corresponding alarm signal, and the output area of sensor that can be by microprocessor is set.

Dead electricity: output normally closed contact.

Sensor abnormality: " measurement " LED flash on output normally closed contact+control panel.

Well heater is unusual: " heating " LED flash on output normally closed contact+control panel.

Scavenger fan is unusual: " fan " LED flash on output normally closed contact+control panel.

After wiring is finished, at controller right flank power-on switch, through the built in self testing of blink, " measurement " lamp is bright on the panel, the data of six charactron displays temperatures and relative humidity illustrate that self check passes through, and equipment changes over to automatically to ambient temperature and humidity observing and controlling state.

6 LED charactrons are arranged, displays temperature value and rh value during measurement on the display screen panel; Displays temperature higher limit during setting, lower limit, upper limit return difference value, lower limit return difference value; Humidity value, the return difference value.

6 LED luminotrons are arranged on the display screen panel, and wherein the luminotron of indication " bound " and " return difference up and down " is the red and green color luminotron, and all the other are monochromatic red luminotron.Display screen panel is provided with 4 buttons, and is used for parameter is set.

Claims (1)

1. digital Temperature and Humidity controller, it is characterized in that constituting by digital temperature sensor, digital humidity sensor, microprocessor and display screen, digital temperature sensor and digital humidity sensor directly are connected the input end of microprocessor, the output termination display screen of microprocessor.
