The Hibiscus Sense is an Internet of Things (IoT) development board powered by the mighty and popular dual-core ESP32 microcontroller, embedded with 3 sensors (APDS9960, BME280 & MPU6050) and 2 actuators (Buzzer & LED / RGB LED), makes it easy for you to kick start your awesome IoT project. Since the microcontroller is the mighty ESP32, this development board is compatible to be programmed using tools such as Arduino IDE (for Arduino programming language), Thonny IDE (Micropython programming language) or ESP-IDF (C, C++ programming language), simply use the latest USB Type-C to program the microcontroller, which has built-in USB-to-Serial converter (Silicon Labs CP2104) with automatic bootloader reset, so you don’t have to press the RESET button each time to upload the program into the microcontroller.
The ESP32 microcontroller comes with 4 MB of SPI Flash running at 240MHz, support both WiFi and BLE connectivity and also the ESP-NOW protocols, which develop by Espressif for low-power 2.4GHz wireless connectivity. The variety of connectivity gives you the freedom and flexibility to develop wireless sensor platform using Hibiscus Sense to be connected to other wireless connectivity such as the BLE on your smartphone, to visualise the data on the mobile app. It’s indeed perfect for your wireless or IoT projects.
Hibiscus sense comes with pre-assembled header makes it easy for you to plug the board on top of the breadboard or on the female header on your DIY PCB projects. There are plenty open GPIOs for you to work with digital inputs and outputs, analog inputs and outputs and multiple extra peripherals, such as UART the RX/TX, I2C and SPI.
Hibiscus Sense is the best board for those who work out for data science and data exploration, as it can easily generate real-time data from rich profusion of sensors on board. The sensors, enables you to sense the physical movement and environment around the board, which total of 13 parameters can be measured:
- APDS9960 – An environment sensor, which sense proximity, colour and gesture.
- MPU6050 – 6 Degree of Freedom (DoF) IMU (Inertial Measurement Unit), the accelerometer and gyroscope.
- BME280 – An environment sensor, which measure the altitude, barometric pressure, humidity and temperature.
- ESP32 running at 240MHz
- 4MB SPI flash and 520 KB SRAM
- USB Type-C with Silicon Labs CP2014 USB-to-Serial converter with automatic bootloader reset.
- Integrated WiFi, Bluetooth and ESP-NOW wireless protocols
