Frequently Asked Questions
Q: What is the difference between an integrated transceiver (RT) ultrasonic sensor and a separate TX/RX pair?
A: An integrated transceiver (RT) sensor like the TCT40-16 combines both the transmitting and receiving elements into one single probe. This simplifies circuit design and reduces the number of components needed. Separate TX and RX modules use two distinct probes — one to send and one to receive — which can offer greater range flexibility but require more wiring and mounting space.
Q: Is the TCT40-16 compatible with Arduino and Raspberry Pi projects?
A: Yes. The TCT40-16 40KHz ultrasonic transceiver sensor is compatible with popular microcontroller platforms including Arduino and Raspberry Pi when used with appropriate driver circuitry. Its 2-pin configuration and wide driving voltage (up to 30V) make it versatile for a range of DIY electronics and automation builds.
Q: Can these sensors be used outdoors or in wet environments?
A: Yes. The TCT40-16 features a waterproof construction, making it suitable for outdoor or moisture-exposed installations. Its operating temperature range of -20°C to +70°C also allows reliable use across a wide variety of environmental conditions.
Q: How many sensors come in each pack?
A: These integrated ultrasonic transceiver probes are available in packs of 5 or 10 units, making them cost-effective for both prototyping and small-scale production runs.
