Monitor temperature, humidity and luminance changes in the air with the Portable Environment Monitor featuring the Renesas RL78/G11 low pin and internally configurable analog microcontroller (MCU).

Description

Temperature, humidity and luminance changes in the air have a direct impact on human body comfort and emotions; as a result, the detection of these factors is very necessary. Additionally, environment conditions need to be recorded in various scenarios ranging from an agricultural environment investigation to a factory audit and energy saving monitoring activities in offices.

The Portable Environment Monitor is a convenient tool that enables real time tracking of temperature, humidity and luminance that can be reflected on a display. This solution is perfectly suited for an IoT sensor module. By simply using four keys, you can set high/low limits of temperature, humidity and luminance. The set value is saved in data flash and once the value is exceeded, the alarm will buzz and an arrow symbol will be shown on the LCD module.

Key Features

  • Demo board includes the RL78/G11 MCU
  • Flash ROM size of the RL78/G11 is 16KB and the RAM size is 1.5KB
  • Powered by three AAA batteries
  • Detects temperature, humidity and luminance in the air
  • Alarms can be set for the high/low limits of temperature, humidity and luminance
  • The temperature sampling circuit directly uses a linear voltage output temperature sensor
  • The humidity sampling circuit uses a module sensor to acquire humidity
  • The luminance sampling circuit is a series of voltage divider circuits that is composed of a photoelectric transistor and resistance R9.
