This is a small form factor IR camera capable of tracking up to four heat/IR sources.
The applications are plenty and can go from tracking robots with IR transmitters for navigation to light barriers,
determining the direction where the object is going, and working as a flame sensor or tracking heat sources.
It's fully compatible with Arduino with only four wires: two for the power supply and two for I2C.
FireBeetle Board - ESP32 integrates a Dual-Core ESP-WROOM-32 module, which supports MCU and Wi-Fi &Bluetooth dual-mode communication.
The electric current is just 10μA in the deep-sleep mode.
The main controller supports two power supply methods: USB and 3.7V external lithium battery.
And both USB and external DC can charge the Lipo battery directly.
Compute Module 4 IoT Router Carrier Board Mini is an internet expansion board based on the Raspberry Pi Compute Module 4.
When connecting with a gigabit network card via PCle,
it brings Raspberry Pi CM4 two full-speed gigabit network ports and offers better performance, lower CPU usage, and higher stability for a long time work compared with a USB network card.
DFRobot Gravity: Analog pH meter pro-V2 is specifically designed to measure the pH of the solution and reflect the acidity
or alkalinity. It is commonly used in various applications such as aquaponics, aquaculture, and environmental water testing.
Gravity: Analog TDS Sensor/Meter for Arduino is an Arduino-compatible TDS Meter Kit for measuring the TDS value of the water, to reflect the cleanliness of the water. TDS meter can be applied to domestic water, hydroponic and other fields of water quality testing.
Solar Power Manager 5V is a small power and high-efficiency solar power management module designed for 5V solar panel.
It features as MPPT (Maximum Power Point Tracking) function, maximizing the efficiency of the solar panel. The module can provide up to 900mA charging current to 3.7V Li battery with USB charger or solar panel.
