Introduction

The ATTINY817-QTMOISTD is an evaluation board incorporating the Atmel ATtiny817 and an AT42QT2160 capacitive touch controller as well as an ANPS604M11A5 sensor. It is specifically designed to measure soil moisture content within a wide range of soils, from sandy to clay. In addition to this, the board also includes an I2C connector, an external temperature sensor, real-time clock and memory, and a variety of other features, making it suitable for use in a range of applications.

Application Field

The ATTINY817-QTMOISTD can be used in a range of fields, including agriculture, environmental monitoring and horticulture. In agriculture, the board can be used to measure soil moisture content, thereby providing essential data for optimizing crop production. In addition, it can also be used to monitor environmental conditions, such as air temperature, pH and conductivity. In horticulture, the board can be used to measure soil water content and salinity, enabling farmers to optimize fertilization of their crops.

Working Principle

The ATTINY817-QTMOISTD works by measuring the capacitance of the soil sample. This is done by passing an alternating current (AC) signal through the sample and measuring the resulting capacitance. The resistance of the soil sample is then calculated, and this value is then used to determine the soil moisture content.The board is easy to use and provides accurate and reliable data. It is also easy to set up and use, and requires minimal user intervention. It is powered by a 3V battery and includes a power source indicator LED, which blinks when the battery’s power is running low.

Conclusion

The ATTINY817-QTMOISTD is a highly versatile evaluation board incorporating an Atmel ATtiny817 and an AT42QT2160 capacitive touch controller as well as a variety of other features. It is suitable for a range of applications, including agriculture, environmental monitoring and horticulture. The board works by measuring the capacitance of the soil sample, enabling it to accurately measure soil moisture content. It is easy to set up and use and requires minimal user intervention.
