The Vma210 Expansion Board is designed to allow easy access to the interface pins of an Arduino Nano. Each DIO pin or analog pin on the Nano is brought to an appropriate header.

Grove's capacitive humidity sensor (corrosion resistant) is a soil moisture sensor based on changes in capacitance. Compared to resistive sensors, capacitive sensors do not require direct exposure of metal electrodes, which can significantly reduce electrode erosion.

This AA boost module integrates with TI's TPS61032 auxiliary chip, which is capable of producing 5V 1A with input above 1.8V . The only difference between V1 and V2 is to change the output current from 2A to 1A.

Basic breakout board for the TEMT6000 Ambient Light Sensor.

Voltage Sensor Module.

This is a small Force Sensitive Resistor . It has an Active Detection Area of 0.16 "(4mm) in Diameter. This FSR from Interlink Electronics varies its Resistance depending on how much Pressure is being applied to the Detection Area. The stronger the Force, the lower the Resistance. When there is no Pressure Applied to the FSR, its Resistance will be greater than 1MΩ, with the Total Pressure applied to the Resistance it will be 2.5kΩ Two Pins extend from the Bottom of the Sensor, making it friendly to the Breadboard. are simple to set up and great for detecting pressure.

The Vma449 integrates the Voice Recorder ISD1820 and Playback CI to record a single message up to 20 seconds long. The recorded message is stored in the analog flash memory that keeps the message stored even in the event of a power failure. The module has an integrated microphone to record your message and buttons for recording, partial playback or full reproduction of the message functions.

The MQ4 is used in gas leak detection equipment in the consumer and industrial markets, this sensor is suitable for detecting CH4 , natural gas , LNG , avoiding exposure to alcohol, kitchen smoke and cigarette smoke . Sensitivity can be adjusted by potentiometer

LED Charlieplexed Matrix - 9x16 LEDs - Vermelho

This small digital distance sensor detects objects between 2 cm and 10 cm apart. With its fast response time, small size and low current consumption , this sensor is a good choice for detecting non-contact objects in compact PCBs facilitating integration into your project.

This is a simple to use Light Sensor that outputs an analog value from 0 to 5V.
