The BME280 Atmospheric Sensor from Whadda is the easiest way to measure barometric pressure, humidity and temperature.

Voltage Regulator for 5v Step-Up/Step-Down - Pololu

A Whadda Universal Temperature Sensor Mounting Kit, used for measuring indoor and outdoor temperatures, controlling the rise/fall of temperature in homes, equipment, control of temperatures in some processes, visualization of the temperature on your website, control of the temperature of your pool, etc.

The HC-12 433MHz Transceiver is a wireless communication Module, which is based on the RF SI4463 chip, has a built-in microcontroller and can be configured by AT commands, the maximum output power is 100mW (20dBm) and the receiver sensitivity differs from: 117dBm to -100dBm, depending on the transmission speed. Accepts 3.2V - 5.5V and can be used with 3.3V and 5V UART voltage devices.

A Module with GPRS Antenna, operation Wireless and SIM Card.

The ESP32-CAM is a WIFI + Bluetooth Development Card based on the ESP32 Chip, with the additional possibility of using a camera. It is ideal for a variety of loT applications.

The Kit Set of Torix Connectors is widely used in building wiring. By selecting the best insulation material, it is durable, corrosion free, anti-aging, pressure 4kv and against electric shock. It breaks the disadvantage of the traditional wiring method which is problematic in wiring, easy to leak, and easy to corrode.

This ESP8285 ESP M2 Module provides easy-to-use WiFi for any UART port and is compatible with the HC-06 Bluetooth modules. If your project uses Bluetooth, it is very easy to convert it to WiFi. Using the integrated web interface, WIFI-UART communication can be configured for TCP or UDP sockets on any port.

The SparkFun Current Sensor Breakout is a High Precision Card that uses the ACS723 for Moderate AC and DC Current Detection Applications. The ACS723 Sensor uses a Hall Effect Sensor to Emit a Voltage relative to the Current that flows through the IP + and IP- Pins on the Board. The advantage of using a Hall Effect Sensor, specifically, is that the Circuit Being Detected and the Sensor Reading Circuit are Electrically Isolated, which means that although your Arduino is Operating at 5V, the Detected Circuit may be Operating at Higher DC or AC voltages.
