“Very useful project made at school that detects some weather data.
Story
AWS, Arduino Weather Station, provides accurately round-the-clock data for the environment. In particular it is based on an Arduino microcontroller board, and it supports a full stuck of sensors for the analysis of the environment.
The aim
The aim of this control until is to detect a series of data through the sensors described above and to interface it with the user through an LCD screen. The little size of the project “hardware” makes it possible to closed it in a little box made with the lasercut machine.
Water and Snow Level Sensor
Water-level indicator is used to indicate the level of water in over head tank, by using this we can avoid the overflow of water, and at anytime we can know the level of water in tank.
DHT11 Humidity and Temperature Sensor
DHT11 digital temperature and humidity sensor is a calibrated digital signal output temperature and humidity combined sensor, which application-specific modules capture technology and digital temperature and humidity sensor technology to ensure that products with high reliability and excellent long-term stability. The product has excellent quality, fast response, anti-interference ability, low cost and other advantages.
Photoresistor
Photoresistors, also known as light dependent resistors (LDR), are light sensitive devices most often used to indicate the presence or absence of light, or to measure the light intensity. In the dark, their resistance is very high, but when the LDR sensor is exposed to light, the resistance drops dramatically, even down to a few ohms, depending on the light intensity.
LCD I2C 1602 Display
LCD1602 with an I2C bus is a type of serial bus. It is a high performance serial bus which has bus ruling and high or low speed device synchronization function required by multiple-host system. The blue potentiometer on the I2C LCD1602 is used toad just the backlight.
I2C uses only two bidirectional open-drain lines, Serial DataLine (SDA) and Serial Clock Line (SCL), pulled up with resistors. Typical voltages used are +5 V or +3.3 V although systems with other voltages are permitted.
DS1302 Real Time Clock Module
Itis based on the integrated DS1302 inside which there is a real-time clock /calendar and 31 bytes of static RAM. You can see the time format as hh/mm/ss, while the date format is yyyy/mm/dd.
LM35 Temperature Sensor
The LM35 Precision Temperature sensor is a sensor which detecttemperature in very accurate way. The Analog to Digital Converter (ADC)converts analog values into a digital approximation based on the formula ADCValue = sample * 1024 / reference voltage (+5v). So with a +5 volt reference, the digital approximation will = input voltage * 205.
Infrared Receiver and Remote Controller
These two components work together: the ir receiver permits the reception of data from the remote controller. The data depend on which button you want to press. The following buttons have been chosen to assign them to specific functions:”
