Automatic monitor for radon concentration. Our powerful API enables to use your seeRADON sensor with other home automation systems, like starting your ventilation automatically when dangerous RADON levels are reached.
|Sensor||Parameter||Minimum value||Maximum value|
|MEMS||Temperature||-40 °C||+125 °C|
|Humidity||0% RH||100% RH|
|Semiconductor||Radon||0.1 pCi/L|| 1750 pCi/L|

When radon and its degradation products are inhaled, they emit alpha particles, which can damage living cells in the lungs, causing radon-induced lung cancer. Thus, radon is the leading cause of lung cancer among non-smokers, according to EPA estimates. In general, radon is the second leading cause of lung cancer. Radon is responsible for approximately 21,000 deaths from lung cancer each year. About 2,900 of these deaths occur among people who have never smoked 
Picture: Radon circuit and health risk
The purpose of uRADMonitor is to generate completely transparent open data, to raise awareness of environmental issues among the population and to take responsibility in our relationship with the environment. The devices are of Romanian design and are produced in Timișoara. Early monitoring of Radon allows us to take mitigation measures, avoiding the negative impact on our health.

|Enclosure||Rainproof plastic||85x85x50 mm 100grams|
The unit comes in a non-sealed housing. Protect the appliance from rain, snow and water in general because the electronic elements inside are very sensitive. Do not cover the air circulation holes. The sensor must not be exposed to strong direct light! This may adversely affect the measurement.
Do not expose the device to large amounts of dust, such as in woodworking centers. Do not expose the device to solvents or a large amount of concentrated chemical vapors (acetone, paints, alcohol, butane, propane, etc.), as the sensors may wear out or the measurements may become inconclusive. Do not expose the device to mechanical shock.
Connect it to power using a 5V micro-USB cable. Use a smartphone or a computer with WLAN capabilities to connect to the local hotspot spawned by your seeRADON unit. The SSID is uRADMonitor-XX, where XX are the last two digits of the Device ID number. The key is the Device ID, in uppercase, as printed on the enclosure. Open 192.168.4.1 in your browser, and click the "WIFI/CONFIG" link to setup the connection to the Internet AP. Enter the SSID and key of your Internet Access Point.
If the connection fails, you will see the status message.
Alternatively, the SSID and KEY can also be configured via USB. Connect to your seeRADON via USB, baudrate 9600bps, open a terminal program and type the two commands: "key1","SSID" then "key2","your WLAN key" . Use the "getsettings" command to verify that the new settings are in place. Quotes are a must, and there are no spaces in between. See the USB Commands manual for more.
