pH Sensor
Features
Use the pH Sensor just as you would a traditional pH meter with the additional advantages of automated data collection, graphing, and data analysis. Typical activities using our pH sensor include:
- Acid-base titrations
- Studies of household acids and bases
- Monitoring pH change during chemical reactions or in an aquarium as a result of photosynthesis
- Investigations of acid rain and buffering
- Analysis of water quality in streams and lakes

Proximity Sensor
Overview
Infrared proximity sensor made by Sharp. Part # GP2Y0A21YK has an analog output that varies from 3.1V at 10cm to 0.4V at 80cm. The sensor has a Japanese Solderless Terminal (JST) Connector. We recommend purchasing the related pigtail below or soldering wires directly to the back of the module.

Rotary Encoder Module Sensor KY-040
By rotating the rotary encoder can be counted in the positive direction and the reverse direction during rotation of the output pulse frequency, unlike rotary potentiometer counter, which species rotation counts are not limited. With the buttons on the rotary encoder can be reset to its initial state, that starts counting from 0.
