Today in this article we are going to work with a sensor in the Microwave Radar Sensor series. The HFS-DC06 is a Microwave Radar Sensor that is designed for movement detection, like intruder alarms, occupancy modules, home automation, sea ice… Read More »Microwave Radar Sensor HFS – DC06
A few months back I took a look at some low-cost passive infrared (PIR) motion sensor modules. Since I am fond of sensors, I did a few sensor research and found out about Microwave radar sensors. Luckily, I found this… Read More »Microwave Radar Motion Sensor (HW-MS03)
What is an Electromagnet???? An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. The electromagnet is simply a large coil of… Read More »How to Control Electromagnet Lifting Solenoids Via Arduino, Node MCU….etc!!!
As ultrasonic sensors started being used in cars as reverse parking sensors, manufactures started producing them in bulk which made them easily available in a wide variety of models at cheap prices. We at Probots (www.probots.co.in), sell a wide range… Read More »How to Communicate Waterproof Ultrasonic Sensor AJ-SR04M/JSN-SR04T with Arduino/ESP32
Introduction: Analog TDS Conductivity sensor is used for measuring the TDS value of the water, this TDS values define the cleanliness of the water. It can be used to check the quality of domestic water, hydroponic liquids, and in other… Read More »How To Interface TDS Water Conductivity Sensor Module with Arduino
The nRF52 DK board is excellent for testing and getting products with the nRF52 IC ready. It has an onboard nRF52 BLE IC which can be programmed as a beacon. It can also act as a programmer and be used… Read More »Programming a Custom nRF52 Beacon using nRF52 DK
Build direction: A snap fit built in the direction shown above will be much stronger. It’s important to consider building direction. If possible, try to avoid designing snap-fit cantilevers that are built up from the bed vertically (in the z… Read More »How to design Snap-fit for 3D Printing Enclosures Design Process Part 3
Annular snap-fits The annular snap-fit utilizes hoop-strain to hold a pressed part in place. Common examples of annular snap-fits are bottle and pen caps. With annular snap-fits, it is possible to achieve a waterproof seal around the joint.For the rest… Read More »How to design Snap-fit for 3D Printing Enclosures Part 2
So in this article there are three parts, which will give you a detail concept on snap-fits. Snap-fit joints are a quick and easy way of connecting two 3D printed components together using interlocking features. snap-fit is an assembly method… Read More »How to design Snap-fit for 3D Printing Enclosures Part 1
Modbus is a data communication protocol originally published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers(PLCs). Modbus has become a de facto standard communication protocol and is now a commonly available means of connecting… Read More »RS-485 MODBUS Serial Communication using Arduino UNO as Slave Part 2
