The chip can also turn off the module by software, and the standby current is close to zero, so that the power supply can always be maintained..
The standard I2C compatible communication interface can transmit the collected data to A-rduino, KL25Z and other microcontrollers for heart rate and blood oxygen calculation..
Alivonao Aquarium Plants Seeds, Live Aquarium Grass Seeds for Fish Tank Freshwater, Fast Growing Aquarium Carpet Seeds Mini Leaf &
High germination rate: After many generations of cultivation, these seeds have had a stable, high-quality survival rate..
Easy to plant: Just spread the seeds on the soil, sprinkle water daily to ensure humidity and the temperature is around 82°F for 5-7 days to germinate, and 15 days to complete the landscaping. Great for newbies..
Highly Adaptable: Seeds can grow in soil, sand and fine gravel to meet any of our landscaping conditions..
Beautiful Environment: Aquatic plants not only produce oxygen to increase the oxygen concentration in the water, but also create a fantastic environment for your fish. They can travel freely in the aquatic forest..
NOTE: Please read the "Plant Methods" description section below carefully. The wrong planting method can affect the growth of the seeds..
Lunarlipes Handheld Carbon Monoxide Meter, Portable CO Gas Detector, CO Gas Tester with LCD Backlit Display, 0-1000PPM High Precision 1PPM Resolution (Battery Not Included) (Orange)
【POWERFUL FUNCTIONS】Portable Carbon Monoxide Meter can continuously monitor the CO concentration in the surrounding environment. Ensure excess CO gas is detected and operators are alerted to take action. And it has 4 modes, which can be easily switched according to the working environment..
【ACCURACY & DURABILITY】 The high-precision Carbon Monoxide Detector has an automatic calibration function. The measurable CO concentration range is 0~1000PPM (accuracy 1PPM).
when the CO gas concentration reaches the alarm level, the sound and light alarm will work. It can measure the ambient temperature with two temperature units (℃ and ℉) (temperature range: 0~50℃/32~122℉). Made of high-quality ABS engineering plastic, it feels comfortable and durable. The sensor life is up to 3 years..
【PRACTICAL DESIGN】Handheld Carbon Monoxide Meter is small in size (5.31 X 1.97 X 1.38 in) and light in weight (3.14oz/0.17 lb), making it easy to carry and operate. The high-definition LCD backlit screen makes it easy to read even at night. In addition, you can also set whether to enable automatic shutdown (when the automatic shutdown function is enabled, if there is no operation within 10 minutes, it will automatically shut down to save power)..

Handheld Carbon Monoxide Meter, Portable CO Gas Detector, Gas Tester with 0～1000ppm Range, 1PPM Resolution(Battery NOT Included)
PROFESSIONAL TOOL: The gas detector is a device that detects the presence of CO gases in an area, often as part of a safety system. The professional detector can continuously monitor the CO gas concentration accurately in the surrounding environment. This type of equipment is used to detect a gas leak and interface with a control system so a process can be automatically shut down..
POWERFUL FUNCTION: Sound alarm works when CO gas concentration reaches the level of the alarm. The concentration of alarm value can be freely set. Auto shut off in 10 minutes without any operation. With a wide measuring range, the ambient temperature can be measured in 2 temperature units (°C and °F)..
HGIH QUALITY：This CO detector has a large LED backlight screen that allows users to easily cope with harsh environments such as darkness, making it easy to read and free users from time and place constraints. Adopt of ABS engineering plastics with high toughness, wear-resistance and stability, with a low power consumption and high precision..
HANDHELD SIZE: The CO gas meter is compact and lightweight, professional designed to fit comfortable in your palm，easy to carry and operate..
WIDELY APPLICABLE: The Gas detectors can be used to detect combustible, flammable and toxic ....
