Tech Express 20Pcs A3144 A3144E OH3144E Hall Effect Sensor, by
The A3144 is an integrated Hall effect non-latching sensor. Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulation and size. A hall effect sensor is much smaller, but can handle less current than a reed switch. The device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitt trigger to provide switching hysteresis for noise rejection, and open-collector output. An internal bandgap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range. If a magnetic flux density larger than threshold Bop, the output is turned on (low). The output state is held until a magnetic flux density reversal falls below Brp causing the output to be turned off (high) (see datasheet bellow). Features: Superior Temp. Stability for Automotive or Industrial Applications 4.5 V to 24 V operation, works with most unregulated supplies Open-Collector 25 mA output, compatible with digital logic Reverse Battery Protection Activate with Small, Commercially Available Permanent Magnets Solid-State Reliability Small Size Resistant to Physical St...

bayite DC 5-120V 100A Mini Digital Current Voltage Amp Meter Ammeter Gauge with Hall Effect Sensor Transformer
bayite Hall effect current meter reads current by detecting the magnetic field around the wire, there is no electrical contact which eliminate risk to delicate monitoring equipment and also minimizes safety concerns. The sensor doesn't get hot like the current shunt sense resistor which can have thermal temperature heat dissipation issues. Three display modes: 1, alternately display Amps and Voltage 2, only display Amps 3, only display Voltage Specifications: Measurement Range: + -100A Accuracy: + - 1% Resolution: 0.3A Working Current: 7-15mA Power Supply: DC 5-120V Overall Dimensions: 48mm*29mm*23mm Cutout Size: 45.5mm*25.5mm Inner Diameter of the Sensor: 19mm Operating Temperature: -4°F - 140°F (-20°C - 60°C) As the resolution is 0.3A, the current reading might be flickering with 0.3A difference. For example, if the current is 1.7A, you might see a 1.7A and 2.0A alternatively. This is normal. If your signal is too weak or you are not getting the resolution you want, you can coil the wire through the current sensor as many times as you want to double, triple, or quadruple the sensitivity or resolution.For example, if your current signal is only 0.2 Amps, you could loop the wire through the sensor 10 times and the signal would by 10X stronger and would appear as 2.0 Amps.
