Octopus Analog UV Sensor (GUVA-S12SD)
ELECFREAKS Octopus Analog UV Sensor (GUVA-S12SD) is the UV electric brick in our Octopus series, the basic design is from the Octopus electric bricks, and the setting of its outlook, the PCB fixing hole, and the connectors are the same.
It can measure the total UV intensity of the sunlight; linear signal voltage output; and it can be used as UV dosimeters, UV index instruments, and flame detection, etc,

Octopus CO2 Gas Sensor (MG811)
Octopus MG811 CO2 Gas Sensor is a CO2 electronic brick in our OCTOPUS series, the basic design for the outlook, PCB fixing holes and connections are the same as theirs.
The higher the CO2 concentration is, the lower the output voltage would be. The users can read the CO2 value easily after checking our brochures and coding samples.
The CO2 probe is made with an industrial grade that is highly allergic to CO2 and anti-interference to alcohol and CO. It is of high performance and quick response with a loaded signal amplification circuit even in different temperature and humidity environments. Besides, the heating circuit on-board helps to convert to stable 6V voltage from 5V directly improves the adaptability of the module.

Octopus LM35 Analog Temperature Brick
This brick uses the LM35D LM35 Precision Centigrade Temperature Sensors from TI. The LM35 series are precision integrated-circuit temperature devices with an output voltage linearly- proportional to the Centigrade temperature. The LM35 device has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from the output to obtain convenient Centigrade scaling. The LM35 device does not require any external calibration or trimming to provide typical accuracies of ±1⁄4°C at room temperature and ±3⁄4°C over a full −55°C to 150°C temperature range. Lower cost is assured by trimming and calibration at the wafer level. The low-output impedance, linear output, and precise inherent calibration of the LM35 device make interfacing to readout or control circuitry especially easy. The device is used with single power supplies, or with plus and minus supplies. As the LM35 device draws only 60 μA from the supply, it has very low self-heating of less than 0.1°C in still air. The LM35 device is rated to operate over a −55°C to 150°C temperature range, while the LM35C device is rated for a −40°C to 110°C range (−10° with improved accuracy).
