This sensor measures soil moisture levels by capacitive sensing, rather than resistive sensing like other common types of moisture sensor. It is made from a corrosion-resistant material giving it a long service life. Simply insert it into the soil and impress your friends with the real-time soil moisture data! The sensor includes an on-board voltage regulator which gives it an operating voltage range of 3.3 to 5.5V. It is compatible with low-voltage MCUs (both 3.3V and 5V logic). To make it compatible with a Raspberry Pi, an ADC converter is required. The sensor is compatible with the DFRobot 3-pin 'Gravity' interface, so it can be directly connected to the Gravity I/O Expansion Shield. * Capacitive soil moisture sensor * Use as part of a plant watering system or monitor * DFRobot type SEN0193 https://elecena.pl/product/27256394/dfrobot-sen0193-gravity-analog-capacitive-soil-moisture-sensor 2024-11-13 https://elecena.pl/product/27256394/dfrobot-sen0193-gravity-analog-capacitive-soil-moisture-sensor 2025-03-26 https://elecena.pl/product/27256394/dfrobot-sen0193-gravity-analog-capacitive-soil-moisture-sensor 2025-05-09 https://elecena.pl/product/27256394/dfrobot-sen0193-gravity-analog-capacitive-soil-moisture-sensor 2025-06-14 https://elecena.pl/product/27256394/dfrobot-sen0193-gravity-analog-capacitive-soil-moisture-sensor 2025-07-23 https://elecena.pl/product/27256394/dfrobot-sen0193-gravity-analog-capacitive-soil-moisture-sensor 2025-09-02 https://elecena.pl/product/27256394/dfrobot-sen0193-gravity-analog-capacitive-soil-moisture-sensor 2026-03-22
