NOTE: This is a basic set for use with your existing WeMos / D1 mini PRO boards. If you want a D1 mini PRO included in the kit, please order the Complete set instead.
The IoT KIT1 includes:
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.
