Frequently Asked Questions
Q: How far can the wireless sensor transmit to the display console?
A: The ALLOYSEED TS-FT0423 wireless sensor can transmit up to 100 meters in open air (line of sight). Under typical indoor conditions with walls and obstacles, a range of approximately 30 meters is expected. Place the sensor and console within this range for reliable readings.
Q: What batteries does the TS-FT0423 thermometer and humidity monitor require?
A: Both the display console and the remote wireless sensor each require 2 × AAA 1.5V batteries. Alkaline batteries are recommended for general use; for cold outdoor environments below -20 °C, lithium AAA batteries are recommended in the remote sensor for extended battery life. Batteries are not included.
Q: Can I use this thermometer hygrometer outdoors year-round?
A: Yes. The remote wireless sensor is designed to measure outdoor temperatures ranging from -40 °C to 60 °C, making it suitable for a wide range of climates. For sub-freezing environments below -20 °C, switch to lithium AAA batteries in the outdoor sensor to maintain optimal performance.
Q: How do I switch the temperature display between Celsius and Fahrenheit?
A: To switch between °C and °F, first remove the batteries from the base station, then press the C/F button to select your preferred unit, and finally reinsert the batteries. Pressing C/F while batteries are installed will not change the temperature unit.
