Wemos Lolin

WEMOS is an IoT specialist that creates microcontrollers and breakout boards based on the ESPressif 32 and 8266. Internet of Things will allow the end user to connect multiple sensors and devices to create a mesh network of sensors and controllers, offering embedded computing devices in everyday objects. IoT can be confusing and requires detail knowledge of networking and microcontroller programming.

WEMOS simplifies this process by offering preprogrammed ESP devices that are already supported on the Arduino IDE, the only knowledge the end user requires is some familiarity using Arduino microcontrollers and programming using the Arduino IDE. The only dependencies are the libraries which can be found in the library manager of the Arduino Software!

This is a PIR sensor module that supports ESP32 and ESP8266 IOT development boards. These Mini Passive Infrared Sensors work exactly like their bigger brothers, however they take about a fifth to half the size compared to its counterpart! PIR sensors are pyroelectric, meaning that when a motion is detected from the change in the infrared levels it will report active high signal to indicate presence of movement. When there is no movement it will be active low offering a 0v signal to indicate there is no movement near it. Once the unit is triggered you must wait 8 seconds for it to reset.

This neat little shield mounts on the WEMOS-D1 Mini and allows the user to power the controller using a 3.7VDC LiPo Battery. It is not only capable of charging the battery but also powering the board with a micro USB cable or with any 5VDC power adapter. A resettable fuse triggers and shuts down the system when the amperage drawn exceeds 1A whenever there is a short or too much amperage drawn from the battery.

This shield is designed for the WEMOS Mini/Mini Pro D1 and allows for precise measuring of atmospheric pressure and can be connected over WiFi. This shield uses the Bosch BMP180 to measure barometric pressure and temperature from an I2C 3.3V WEMOS Microcontroller. Combined with a WEMOS board, this information can be communicated via internet and be used to control a system. The programs are compiled using WEMOS XI expansion in Arduino.

The DS1307 serial real-time clock is a low power, small packaged yet powerful calendar. Data is transferred in Serial via I2C. The clock is capable of providing seconds, minutes, hours, day, date, month, and year data. The clock operates in either the 24-hour or 12- hour format with AM/PM indicator. In addition, the end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The DS1307 has a built-in power-sense circuit that detects power failures and automatically switches to the backup power supply. It is great to be used with your Arduino-related projects! Battery is included.

If you're interested in making your project connect to the web and be part of the grander scheme of IOT (Internet of Things), then this board is the gadget for you! Like other microcontrollers and microprocessors, the ESP32 has built in power regulation circuits, onboard antennas, noise filters and fits snuggly onto any breadboard for rapid prototyping. The ESP32 can interface with other MCUs as master or slave, or function completely standalone through SPI/SDIO, I2C and UART. The microcontroller can also support an SD card and multiple sensors with its 32 GPIO pins (all of which can be used for PWM). This microcontroller has TWO microprocessor inside the metal RF shield as one will act as the co-processor. You have the capability of turning off the main processor when not in use to save power.
