This RC522 RFID Kit includes a 13.56 MHz RF reader module that uses an RC522 IC and two S50 RFID cards to help you learn and add the 13.56 MHz RF transition to your project. The MF RC522 is a highly integrated transmission module for contactless communication at 13.56 MHz. RC522 supports ISO 14443A/MIFARE mode. The module uses SPI to communicate with microcontrollers. The open-hardware community already has a lot of projects exploiting the RC522 – RFID Communication, using Arduino. Features Operating Current: 13-26 mA/DC 3.3 V Idle Current: 10-13 mA/DC 3.3 V Sleep Current: <80 uA Peak Current: <30 mA Operating Frequency: 13.56 MHz Supported card types: mifare1 S50, mifare1 S70 MIFARE Ultralight, Mifare Pro, MIFARE DESFire Environmental Operating Temperature: -20-80 degrees Celsius Environmental Storage Temperature: -40-85 degrees Celsius Relative humidity: relative humidity 5% -95% Reader Distance: ≥50 mm/1.95' (Mifare 1) Module Size: 40×60 mm/1.57*2.34' Module interfaces SPI Parameter Data transfer rate: maximum 10 Mbit/s Included 1x RFID-RC522 Module 1x Standard S50 Blank Card 1x S50 special-shaped card (as shown by the keyring shape) 1x Straight Pin 1x Curved Pin Downloads Arduino Library MFRC522 Datasheet MFRC522_ANT Mifare S50

NFC is a popular technology in recent years. Almost all the high-end phones in the market support NFC. Near field communication (NFC) is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters. This module is built around NXP PN532. NXP PN532 is very popular in the NFC area. Makerfabs developed this module based on the official document. A library for this module is available. Features Small dimension and easy to embed into your project Support I²C, SPI, and HSU (High-Speed UART), easy to change between those modes Support RFID reading and writing, P2P communication with peers, NFC with Android phone Up to 5~7 cm reading distance On-board level shifter, Standard 5 V TTL for I²C and UART, 3.3 V TTL SPI Arduino compatible, plugin and play with our shield RFID reader/writer supports Mifare 1k, 4k, Ultralight, and DESFire cards ISO/IEC 14443-4 cards such as CD97BX, CD light, Desfire, P5CN072 (SMX) Innovision Jewel cards such as IRT5001 cards FeliCa cards such as RCS_860 and RCS_854 Downloads Usage NFC Library

This kit is based on ESP32 and LoRa. The ESP32 3.5' display is the console for the system, it receives the LoRa message from LoRa moisture sensors (support up to 8 sensors in the default firmware) , and send control commands to LoRa 4-channel MOSFET (2 4-channel MOSFET supported, with totally 8 channels), to control the connected valves open/close, and thus to control the irrigation for multiple points. Features Ready to use: Firmware are pre-programmed for all the modules before shipping, the user can only power them up and set the ID to the console, and start to use. Suitable for none-programmers, in 3 minutes to create filed application. With Lora wireless connection: The monitor & control range can be up to few kilometer, suitable for garden/small farm. Soil moisture sensor with good corrosion resistance, can be used at least half an year with 2 AAA battery. Easy to install: Compares to cheap solution with wires, which is hard to implement in files application, there the connection wires do not needed, the whole installation clean and easy; The valves can be connected Lora MOSFET easily. Hardware & Software Open: To study Lora & FreeRTOS. The ESP32 display console/Lora Soil Moisture Sensor/LoRa MOSFE are all programmed with Arduino. For programmers/engineers, can development further more specialized application. Based on ESP32, with WiFi connection, the console can also access to internet, the create much more applications including the moisture data updating to internet for remote monitor, and remote control with MQTT. Included 1x ESP32 3.5' Display (without camera) 1x Lora Expansion for ESP32 Display 2x Lora Moisture Sensor 1x Lora 4-channel MOSFET 1x 12 V Power Supply Water Pipe (5 m) 1x 1-input & 4-output Pipe Joint Downloads Instructable: Soil Monitoring & Irrigation with LoRa GitHub

This air monitor is specifically used for monitoring greenhouses. It detects: Air temperature & Humidity CO2 concentration Light intensity Then transmit the data via LoRa P2P to the LoRa receiver (on your desk in the room) so that the user can monitor the field status or have it recorded for long-term analysis. This module monitors the greenhouse field status and sends all sensor data regularly via LoRa P2P in Jason format. This LoRa signal can be received by the Makerfabs LoRa receiver and thus displayed/recorded/analyzed on the PC. The monitoring name/data cycle can be set with a phone, so it can be easily implemented into the file. This air monitor is powered by an internal LiPo battery charged by a solar panel and can be used for at least 1 year with the default setting (cycle 1 hour). Features ESP32S3 module onboard with the WiFi and Bluetooth Ready to use: Power it on directly to use Module name/signal interval settable easily by phone IP68 water-proof Temperature: -40°C~80°C, ±0.3 Humidity: 0~100% moisture CO2: 0~1000 ppm Light intensity: 1-65535 lx Communication distance: Lora: >3 km 1000 mAh battery, charger IC onboard Solar panel 6 W, ensure system works Downloads Manual BH1750 Datasheet SGP30 Datasheet
