Abstract

Hotplate magnetic stirrer is a laboratory tool that is used to heat or warm as well as mix or homogenize chemical solutions. This tool is available in chemical, microbiology and pharmaceutical laboratories. Equipped with a stirrer made of magnets (stir bar) which is used to homogenize chemical solutions. This magnetic stirrer hotplate uses an ATMega 16 microcontroller based system. It uses an infrared temperature sensor MLX90614 to measure and monitor the temperature of the solution, starting from the start of mixing which is assisted by rotating a DC motor as a stirring device until the liquid is mixed or homogeneous. Homogeneous conditions are indicated by the ADC value ( Analog to Digital Convertion) which is obtained constant. If you use the automatic menu, only choose the mixing solution on the automatic menu. There are four choices for the solution speed of 400-1600 rpm with an increase of 400, there are four temperature choices, namely 30-60 degrees Celsius in increments of 10, there is a choice of time used for stirring time at 1-30 minutes. For temperature display, stirring speed and stirring time can be seen on the LCD 20x4 display.

Abstract

The development of communication networks is very useful in daily activities such as wireless data communication, monitoring and system security. In this case, a wireless sensor network technology is known, which is very suitable when applied to a system with a large number of nodes and spread over a large enough area at a low cost. This wireless sensor network is a wireless communication network that supports communication between sensor nodes in a considerable distance by placing several sensors in an area. Generally, this Wsn consists of a sensor node and a server node in the form of a personal computer. The data from the reading of the CO gas value will be sent directly from the sensor node to the node server. This device is built using the nRF24L01 module and the CO gas sensor using the MQ-7 sensor. This wireless sensor network communication system is built using multihop. From the activities it can be concluded that the success of sending data is influenced by the distance and number of nodes working on a topology, with the amount of data sent which is influenced by long distances and the large number of nodes, not all data is successfully received because of the large number of data collisions from each node.
