## Overview

The Robocraze Voltage Transformer Module is a single-phase AC voltage sensor designed for Arduino-compatible boards. It measures voltages up to 250V AC with a linear range of 0-1000V and outputs an adjustable analog signal. Featuring a micro-precision onboard transformer and PCB mounting pins longer than 3mm, it offers reliable voltage and power measurement capabilities for professional and hobbyist electronics projects.

## Description

Water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signal. This one is suitable to detect flow in water dispenser or coffee machine. Flow rate range: 2-100l/min water pressure resistance: = >2mpa operating temperature: = -20-85c insulation resistance: = >100m characteristics of flow pulse: F=(4.8 x q) q=l/min accuracy: ±3 percent connector type: G1

Review: Its not easy to implement. - Although there are lots of writeups and videos in how to implement this module, I couldn't get it working. If you are looking for ac volt sensor which can be implement easier, I recommend pzem 004t instead even if it's costlier.
Review: Not reliable - The voltage readings are usually not reliable. No matter what trim or settings you use ! I tried matching the trim value to the actual voltage reading(using voltmeter): then it gave correct readings only for a while- after which 220 V suddenly became 150 volts

## Features

- Within 250 v ac voltage can be measuredLinear range: 0-1000v 0-10ma(sampling resistor is 100ohm) installation: Pcb mounting (pin length> 3mm)
- Onboard micro-precision voltage transformerRatio: 1000:1000
- Analog output corresponding quantity can be adjusted
- Good consistency, for voltage and power measurement
- The ac voltage sensor can detect an electric fieldMost of the detection can be done by a simple capacitor., Package contents: 1 sensor module for arduino
