ESP32 is a compact size, a low-powered microcontroller that comes with an integrated Wi-Fi and dual-mode Bluetooth. The dual-mode supports both Bluetooth Classic and Bluetooth Low Energy (BLE). BLE offers a lesser latency than Classic Bluetooth and consumes less power. With an additional of 10 capacitive touch GPIOs, it becomes easy to trigger an event, such as waking up ESP32 from a deep sleep and much more. Let’s have a look at the best 3 ESP32 projects submitted to PCBWay in January 2021.
Security System with notifications
It is a perfect project to create an economical home security system on your own. All you need is an ESP32 development board, a PIR sensor, and a relay module. As soon as the PIR sensor detects any movement, the circuit lights up a 220V LED bulb using a relay module. Along with this, it sends an alert notification to the telegram app installed on your device. The sensitivity of the PIR sensor is easily adjustable in the program code.
PCB details
It is a rectangular single-layer PCB, ordered from PCBWay. The solder mask is white and is consistent throughout the board. That makes the quality of the PCB superior. The FR-4 substrate makes the board strong, water-resistant and provides better insulation.

Security System
E-paper dashboard
Do you often forget some of the important dates or events due to your busy schedule? Well, then this project is a lifesaver for you. Along with tracking the dates, this E-paper dashboard also tells about the climatic conditions of your area. So before stepping out of your house, you are prepared for the worst. With the deep-sleep feature of ESP32, the battery lasts up to 4 months on a single charge. So, needless to worry about charging it now and then.
PCB details
It is a 50×44 mm rectangular PCB board. The black solder mask on the surface protects the board from oxidation. It also prevents forming of solder bridges between closely spaced solder pads. The perfect copper tracing allows all the components to connect easily on the board. PCBWay provides the best boards in terms of their appearance and quality.

Motor Driver Shield
It is an exciting project that lets you control an RC car via an android app. What’s more? This RC car contains an ESP32 powered camera. That gives you a new outlook to see the world. The app enables the car’s movement in any direction and also shows the visual of the camera. For night-mode vision, it uses an LED light. The camera also features the negative-mode that will make your old memories of clicking pictures refreshed.
PCB details
It is a two-layer PCB board with a thickness of 1.6mm. The solder mask is green, while the silkscreen is white. And that completes the PCB in a dimension of 68.6×53.3mm. With superb quality, PCBWay provides the freedom to design a PCB according to your need. With its on-time delivery, PCBWay ensures the PCB reaches you on time so that your interest in creating new projects never dies.
