HM TDS 3 Meter is the accurate test instrument for the measurement of TDS of aqueous solutions. It has a built-in sensor for Automatic Temperature Compensation (ATC).

Simply immerse the meter in the water sample and it will display the TDS reading in parts per million (ppm) or milligrams per liter (mg/L). It comes with a black vinyl carrying case and it will protect your meter in every way.

This is the HC-SR04 ultrasonic distance sensor. This economical sensor provides 2cm to 400cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3mm. Each HC-SR04 module includes an ultrasonic transmitter, a receiver and a control circuit.

There are only four pins that you need to worry about on the HC-SR04: VCC (Power), Trig (Trigger), Echo (Receive), and GND (Ground). You will find this sensor very easy to set up and use for your next range-finding project!
