IoT KIT 1 - WeMos D1 mini PRO ESP8266 32Mb flash, with basic shield sets: Dual Base Shield ProtoShield Button Contact Relay Data Logger DHT11 for Arduino IoT kit WiFi projects
This kit is specifically designed to use Arduino in the Internet of Things. No matter if you’re a beginner or a professional, this kit will let you unleash your creativity! It contains a set of modules and sensors necessary to build your own IoT projects. Among possible applications are the temperature and humidity monitoring, external devices control, data collection and logging (with real-time clock), and many more!
The IoT KIT1 includes:
WiFi D1 mini PRO is an integrated ESP8266-based WiFi-enabled microprocessor unit equipped with 32Mb (megabits) of flash memory.
It is pin-compatible with the WeMos D1 mini / mini PRO boards.
WiFi D1 mini PRO comes with an embedded CERAMIC WiFi antenna on-board, and has a connector for an optional external antenna.
The input power can vary from 4 to 9V DC (supplied to the «5V» pin). We recommend to supply exactly 5V in case of using external shields requiring 5V operation. The unit can also be powered directly from the USB port. Alternatively, you can power the WiFi D1 mini PRO from a stabilized 3.3V source by connecting it to the «3.3V» pin on the PCB.
PC communication is done via CP2104 (USB-TTL). Corresponding driver may need to be installed on your system.
In order to use WiFi D1 mini PRO with an Arduino IDE, please use the ESP8266 library.
DHT11 is an accurate and inexpensive the Temperature and Humidity sensor shield. The sensor includes an 8-bit ADC and provides reliable output results. It covers the needs of most home and everyday application conditions.
A very common Contact Relay to control the AC (light, home equipment, etc.) or DC load using WeMos / WiFi D1 mini PRO board. Control pin of Relay is connected to the D1 I/O port on the D1 mini. If you wish to use another I/O port, just cut off of the connection to D1 and solder it to another pad, as needed.
Data Logger and RTC Shield for WeMos / WiFi D1 mini PRO. This shield allows you to store data on an SD card. The included RTC (Real Time Clock) can be used to add a timestamp, so that you know the exact time of each record! The coin cell backup battery keeps the real time clock going even when the power is disconnected. The real-time clock has reverse polarity protection.
SD card pinout:
Button is a commonly used shield with a great variety of applications. By default, the button is connected to D3 I/O port on the WiFi D1 mini. If you wish to use another I/O port, just cut off of the connection to D3 and solder it to another pad, as needed.
The Dual Base Shield is designed in a way so that you can connect another shield to the WeMos / WiFi D1 mini PRO without having to use the normal stacking method. This is useful when you have multiple shields that are not suited for stacking together (like relay shields), or where a lower profile is preferred.
The Proto Shield is designed for use with the WeMos / WiFi D1 mini PRO boards. It allows you to build your own custom shields and plug them directly into the WiFi D1 mini PRO. With the pin headers supplied, you can also stack multiple shields on top of each other.
High quality USB Type A (m) to micro USB Type B (m) cable.
Cable length: 50cm (about 19.5 inches).
