A soil moisture monitoring system is a collection of devices that can detect soil moisture, read or store data, and transmit data to a computer, which can then organize, visualize, and interpret the data. The optimal water level in the soil is fundamental to plant growth. The soil moisture monitoring device is designed to evaluate and control the amount of water needed to maximize crop quality while conserving water resources during irrigation. The device is made up of a steel metal probe profile sensor, an arduino mega, a microSD card shield, a real-time clock, and a graphic display. Moisture resolution is 0.02%. The calibration can be done at any location depending on the type of soil and the first principle used.

Abstract: In a savanna climate, the soil surface is tilled solely to reduce evaporation during the dry summer period. Where models exist for predicting water and heat movement through soils, soil conductivity, thermal diffusivity, and soil bulk density are required. To overcome difficult physical properties of soil, the soil temperature measurement was designed and built directly and accurately with locally sourced materials. Six semiconductor temperature (DS18B20) sensors, a tipping bucket, a graphic display, a real-time clock, a miscroSD card shield, and a microcontroller comprise the device (arduino mega 2560). The temperature sensor has a resolution of 0.0625 oC and a maximum temperature of 120 oC, making it suitable for measuring soil temperature. The tipping bucket has 0.2794 mm per tipping and a real switch time of 1 ms. The log of the datalogger.

The increase in population in African continent coupled with poor waste management result into high level of air pollution post danger on people. To be able to create a better awareness magnitude of air pollution need to be quantified. To be able to achieve this goal a low-cost gas, dust and weather monitoring device was developed. The device consists of sensing unit (that comprised of gas sensors, dust sensor and weather sensor), microcontroller, real-time clock, MicroSD card shield and graphical liquid crystal display. For analysis, the data is stored in excel format and can be copied directly from MicroSD card. The device was tested and examined through intensive experimental work. The sample data shown on table and plots obtained from the experiment on field display the performance of device, it is clear that there is a close conformity between the data collected by the developed system and the existing standard systems. The need for extra cost and expensive third-party computer software for interfacing to download data from the logger have been eliminated. The system will be helpful in monitoring and recording of gas emission from dump site and atmospheric parameters.
