KTH5641 Magnetic Field Detection Module, Gaussmeter Sensor with 1600GS Range, USB-C Rechargeable Magnetometer Pole Testing, Blue Board(B)

Product description Features:This product uses KTH5641A1 as a sensor. KTHA5641 outputs 0-2.5V when encountering the North Pole and 2.5-5V when encountering the Pole, with a step of 1.5mV/GS.The analog quantity is transmitted to the 51 single-chip microcomputer via the 18-bit AD chip MCP341 to calculate the field strength.The field at both ends of the bar magnet is the strongest, and the field in the middle is the weakest. This is because the bar magnet can be considered to be composed of many tiny needles arranged in the same direction. The lines of force at both ends of the magnet do not completely cancel each other, but the lines of force in the middle cancel each other, resulting in stronger magnetism at both ends.The edge of the circular magnet has the strongest magnetism because its field distribution is similar to that of the bar magnet. The lines of force point from the N pole to the S pole, and the field is strongest at the edge of the end face.Application: force measurementWarm reminder, the same magnet is placed in different positions, and the measured field strength is different. Because the field distribution of the magnet is uneven. The field distribution of the magnet is related to its shape and magnetization direction.Specifications:Part name: KTH5641 field strength detection moduleMaterial: As shownColor: BlueSize: As shownPower supply: Built-in 3.7V lithium batteryCharging way: Charge with mobile phone charger, TYPE-C interface, charging cable provided.Detection range: 1600GS Accuracy: There is no specific accuracy for the time being, please observe the data and the accuracy of the device is about +-5%.Instructions for use (how to use): Turn the power switch to the ON end, and the power indicator light will light up. Press the for Zero button to reset the initial data to for zero. This step is necessary because the field is different in each place. Then use the sensor (on the back of the board) to approach the object to be measured, and the data will be displayed. Charging way: Insert the TYPE-C of the mobile phone charger into the TPE-C bracket on the board, the charging indicator light (red light) will light up, and the indicator light will go out after full.Package content:A: 1*tested motherboardB: 1*tested motherboard + 1*assembled shell Manufacturer Contact Information no
