0.96 Inch OLED White ESP32 WiFi Bluetooth CP2102 18650 Battery Development Board
18650 Lithium Battery, 0.96 Inch OLED Display, Wi-Fi, Bluetooth ESP32 Shield Module, ESP-32 ESP8266 CP2102, Development Board Module
Product Description
- Supporting Lua program, easily to develop.
- Supporting three modes: AP, STA, and AP+STA.
- Small volume, easily embeded to other products.
- Strong function with support LWIP protocol, Freertos.
- High performance-price ratio.
When you do some ESP32 projects you must hate to add a power bank to provide the power. This tiny board could solve such problems. A LG 3000mAH 18650 battery could make ESP32 run 17 hours or more.

The HW-201 IR infrared obstacle detection module can detect obstacles within a distance range of 2 cm to 30 cm, with a detection angle of 35 degrees.
It can operate with a supply voltage of 3.3 V to 5 V and has a maximum current consumption of 100 mA. The module outputs a digital signal, high when an obstacle is detected, low when no obstacle is detected.
The infrared LED has a wavelength of 940 nm and an operating frequency of 38 kHz. The module operates at temperatures between -25 °C and +55 °C.
The SHT3x sensor is the most accurate and precise sensor for measuring humidity and temperature parameters compared to other temperature sensors like LM35, Thermistor, DS18B20 & DHT11/DHT22. Thus SHT3x can be used for industrial applications because of the high accuracy and good sensitivity. Its Relative Humidity operating range is 0 – 100% and Temperature operating range is -40° to +125°C (-40° to +257°F).
The « LJ12A3-4-Z/BX » is an inductive proximity sensor that detects metal objects within a 4mm range. It operates on a DC 6-36V power supply and has an NPN (Normally Open) digital output, meaning it completes a circuit to the signal line when it detects metal. These sensors are used in industrial automation for non-contact switching, control, and detection
