Introduction: Handheld Water Temperature Monitoring System Based on ICStation ATMEGA2560
ICStation team has made this project about Handheld Water Temperature Monitoring System.It works under DC5V voltage. It can detect water temperature through DS18B20 temperature detection module. When the detection temperature is higher than the setting ceiling temperature, or lower than the minimum temperature, the system buzzer will give an alarm and LED light will flash. The system’s manufacture operation is simple and cost is cheap, which is suitable for temperature detection in factories and new agricultural greenhouses
1) When the starting-up hardware initializes, 1602 LCD display module will display the interface which has been setted
2) When the temperature detected by DS18B20 probe is between the minimum and the maximum temperature, buzzer will not give an alarm and LED light won’t flash.
3) When the temperature is higher than the maximum or lower than the minimum, buzzer will alarm and LED will flash.
4)Set the maximum and minimum temperature by three buttons.
