Soil Moisture Sensor Powered by Solar Panel and Super Capacitor

Abstract

With the increase in IoT applications, smart agriculture applications have become widespread. In order to make physical measurements such as humidity and temperature in agricultural areas (rechargeable or non-rechargeable) battery-powered smart sensors are used. However, these battery-powered sensors require periodic battery replacement or charging, resulting in low operating life, additional maintenance and cost. This study aims to solve these problems by proposing a unique electrical supply source for smart sensors. In this article, a soil moisture sensor for agricultural use, which does not require a battery, has been developed by using a super capacitor charged with a solar panel. After this sensor is installed in the field, it does not require periodic maintenance for reasons such as charging or battery replacement. The sensor periodically transmits humidity information to the base station via its wireless module.

Güneş Paneli ve Süper Kapasitör ile Beslenen Toprak Nem Sensörü

Abstract

IoT uygulamalarının artmasıyla birlikte akıllı tarım uygulamaları yaygınlık kazanmıştır. Tarım alanlarında nem ve sıcaklık gibi fiziksel ölçümler yapabilmek için (şarjlı veya şarjlı olmayan) pille beslenen akıllı sensörler kullanılmaktadır. Ancak pille beslenen bu sensörler periyodik olarak pil değişimi veya şarjı gerektirmekte, bu da düşük çalışma ömrü, ek bakım işlemleri ve maliyetine sebep olmaktadır. Bu çalışma akıllı sensörler için özgün bir elektrik besleme kaynağı önererek anılan problemleri çözmeyi hedeflemektedir. Bu makalede güneş paneli ile şarj olan bir süper kapasitör kullanarak pile gereksinim duymayan tarımsal kullanım amaçlı bir toprak nem sensörü geliştirilmiştir. Bu sensör arazide kurulduktan sonra şarj veya pil değişimi gibi sebeplerle periyodik bakım gerektirmemektedir. Sensör, kablosuz modülü aracılığıyla periyodik olarak baz istasyonuna nem bilgisi iletmektedir.
