FAQs
The ESP32-CAM is a small size, low power consumption camera module based on ESP32. It comes with an OV2640 camera and an ESP32-CAM-MB micro usb to serial port adapter.
What is the advantage of ESP32 cam? ›
It adds extra CPU cores, faster Wi-Fi, more GPIO, and supports Bluetooth 4.2 and Bluetooth Low Energy. Additionally, the ESP32 comes with touch-sensing pins that can be used to wake the ESP32 from deep sleep, a built-in hall effect sensor, and a built-in temperature sensor.
What is the work of ESP32 cam module? ›
The ESP32-CAM is a low-cost ESP32 development board with an onboard camera. This is an ideal solution for IoT applications, prototype constructions, and DIY projects. Wi-Fi and low-power BLE are integrated on the board, as well as two high-performance 32-bit LX6 CPUs.
What is the difference between ESP32 and ESP32 cam module? ›
The main difference between the ESP32 and the ESP32-CAM is that the ESP32 is a Wi-Fi and Bluetooth chip with a dual core processor, while the ESP32-CAM is a Wi-Fi and Bluetooth chip with a single core processor and an onboard camera. Additionally, the ESP32-CAM has more memory and storage than the ESP32.
What is the difference between OV2640 and OV3660? ›
3MP. OV3640, OV3660 are 3MP 2048 x 1536 (QXGA) SoC image sensors from Omnivision. They are both upgrade version of the 2MP OV2640. OV3640 is 1/4″ sensor while the OV3660 is cost down version that is 1/5″ sensor.
Can ESP32-cam work without Wi-Fi? ›
Connecting to the ESP32-CAM Access Point
After uploading the code, you can connect to the ESP32-CAM access point to access the web server. You don't need to connect to a router.
What power supply is needed for ESP32-cam? ›
Technical Specifications
| Module Model | ESP32-CAM |
|---|
| Light-sleep: minimum 6.7mA@5V |
| Security | WPA/WPA2/WPA2-Enterprise/WPS |
| Power supply range | 4.75-5.25V |
| Operating Temperature | -20 ℃ ~ 70 ℃ |
26 more rowsFor example, if I'm creating a simple daylight sensor that will turn off my lights automatically, the Raspberry Pi would work, but its size and cost would make it impractical for this application. In this case, the ESP32 would work better as it is smaller, cost-effective, and can get the job done.
Is ESP32 a WiFi module? ›
ESP32-WROOM Series
These modules are well suited for Wi-Fi and Bluetooth/Bluetooth LE-based connectivity applications and provide a solid dual-core performance.
Can ESP32 cam detect motion? ›
Motion detection is the task of detecting when the scene in the ESP32 camera field of view changes all of a sudden. This change may be caused by a lot of factors (an object moving, the camera itself moving, a light change...) and you may be interested in get notified when it happens.
If your project requires WiFi 6 connectivity, you should consider ESP32 C6 else you can consider ESP32 S3 or ESP32 S2. If your project requires BLE5. 2 then you can go with ESP32-S3, ESP32-C3 or ESP32-C6.
Can ESP32 replace Arduino? ›
Arduino Hardware and Architecture
Arduino boards typically offer lower processing power compared to ESP32 but are often sufficient for many applications. Similar to a devkit, the easy-to-use layout and a range of built-in components make them great for beginners.
Which is better ESP32 or Arduino? ›
In terms of connectivity, most Arduino boards don't have Wi-Fi or Bluetooth functionality on their own, and this includes the R4 Minima. They require the use of an add-on Ethernet or Wi-Fi shield. On the other hand, the Esp32 has Wi-Fi capabilities built-in, making it suitable for IoT projects.
What is ESP32 based on? ›
Processors – The ESP32 uses a Tensilica Xtensa 32-bit LX6 microprocessor. This typically relies on a dual core architecture, with the exception of one module, the ESP32-S0WD, which uses a single-core system.
What is the architecture of ESP32 cam? ›
It adopts 7-stage pipeline architecture, on-chip sensor, Hall sensor, temperature sensor and so on, and its main frequency adjustment ranges from 80MHz to 240MHz. ESP32-CAM can be widely used in various IoT applications.
What is the power source for the ESP32 cam? ›
The ESP32CAM is a standalone device that can be powered from either 5V or 3.3v. A step-up booster can be used to step the voltage from the LiPo up to the 5v needed to power the ESP32CAM.
