GSR SENSOR MODULE - Interface: Analog - Operating Power: 3.3V/5V - Sensor: finger straps for electrodes - Dimensions: 20 x 20mm - Various Main Boards Support: Arduino/Seeeduino/Raspberry Pi/BeagleBone/LinkIt ONE - This module stands for galvanic skin response and it is a method of measuring the electrical conductance of the skin. - It can be used to reflect the human emotional activity. When people are emotionally stressed or have strong expressions on the face, sympathetic activity increases and promotes the secretion of sweat glands, which increases the skin’s electrical conductivity. - It allows you to spot such strong emotions by simply attaching two electrodes to two fingers on one hand. In some galvanic skin response devices such as lie detectors, this scientific principle is also applied.

WATER LEVEL SENSOR - Simply, The more water the sensor is immersed in, the higher the output voltage in the signal pin is. - The sensor has a series of ten exposed copper traces. Five are power traces and five are sense traces. These traces are interlaced in parallel so that there is one sense trace between every two power traces. These traces are not connected unless they are bridged by water when submerged. - Operating voltage: DC 3-5V, < 20mA - Judge the water level through with a series of exposed parallel wires stitch to measure the water droplet/water size Price 350 Birr https://vector4engineering.com/product/water-level-sensor/ Address – Megenagna, Zefmesh Grandmall 3rd floor 301 0993802995 Vector/0922787347 Kase VECTOR FOUR ENGINEERING
