Prototype Monitoring Temperature and Humidity Sensor Room Server-Based Internet of Things (IOT)

Computer servers are very important to provide resources to be used for computer users in a network. Temperature and humidity in the server room are things that must be addressed to remain in normal, so as to minimize damage to server computer hardware, a system consisting of secure devices and hard devices using a microcontroller consisting of NodeMCU, DHT11 temperature sensor, LCD I2C, temperature & humidity data will be displayed in real-time on the website and also get notifications via e-mail and telegram if the temperature and humidity exceed the normal limit.
