智能小溫室

Abstract

目的: 現代人上班忙碌，沒有時間照顧植物，那些上班族喜歡種植物就沒空去照顧它，使得植物死亡。所以我們製作了一個小溫室來幫忙照顧植物。 原理: 1.土壤濕度感測器讀取土壤的濕度，如果濕度太低,ESP8266則會讓 抽水馬達啟動，給植物水分。 2.溫溼度感測器則讀取溫室內的溫度及濕度，植物不可能在溫度及濕度過高及過低的情況下生存。如果溫度太高或濕度太高ESP8266會驅動風扇來達到降溫的效果。 3.使用ESP32啟動OV7670鏡頭並連接到網絡，以便在網絡上觀測植物的生長期況。 4.光敏電阻，當光線不足時ESP8266使LED燈亮。 5.使用ESP8266的WIFI功能連接到互聯網，將數據上傳至 ThingSpeak。 6.使用降壓模組把9Vinput電源降壓至5V，為 ESP32,ESP8266等各 項設備供電。 7.使用ADS1115擴充ESP8266的analog input，讓ESP8266 可以 連接更多類比輸出的感測器。 8.用ESP8266控制RELAY模組，控制需要較高電壓驅動的設 備，如 風扇，抽水馬達。

purpose: Modern people are busy at work and do not have time to take care of plants. Those office workers who like to grow plants have no time to take care of them, causing the plants to die. So we made a small greenhouse to help take care of the plants. principle: 1. The soil moisture sensor reads the moisture of the soil. If the moisture is too low, ESP8266 will start the pumping motor to provide moisture to the plants. 2. The temperature and humidity sensor reads the temperature and humidity in the greenhouse. It is impossible for plants to survive under the conditions of too high or too low temperature and humidity. If the temperature is too high or the humidity is too high, ESP8266 will drive a fan to achieve the effect of cooling down. 3. Use ESP32 to start the OV7670 lens and connect to the network to observe the growth period of plants on the network. 4. Photoresistor, ESP8266 will make the LED light bright when the light is insufficient. 5. Use the WIFI function of ESP8266 to connect to the Internet and upload the data to ThingSpeak. 6. Use a step-down module to step down the 9Vinput power supply to 5V to supply power for various devices such as ESP32 and ESP8266. 7. Use ADS1115 to expand the analog input of ESP8266, so that ESP8266 can connect more sensors with analog output. 8. Use ESP8266 to control the RELAY module to control devices that require higher voltage drive, such as fans and pumping motors.
