Wireless sensor PT701 GPRS wireless pressure sensor level sensor
● Hydraulic monitoring
● Water pipe pressure measurement
● Water tank , fuel tank pressure ,level measurements
● Environmental parameter detection
PT701 wireless pressure gauge is a LoRaWAN® wireless pressure transmitter monitors pressure in pipeline, water tank, fuel tank and other occasions. It reports pressure to cloud platform at a configurable time interval, and sends alarm message to platform when the pressure passes beyond alarm threshold or there is a variation in process pressure. The data is sent with LoRaWAN® communication technology which features long-distance communication and low power consumption.
The device can be configured with AT commands via on board TTY serial port. User can configure alarm threshold, network access method OTAA/ABP, network access parameters and etc.
With the corresponding gateway, the device can be connected with all kinds of network servers and IOT platforms,such as TTN, AWS and etc.
The battery-powered wireless pressure transmitter features a low-power design and has the characteristics of long communication distance, long battery life, high measuring accuracy, no wiring, and is widely used on wireless pressure monitor occasions.
The device offers all kinds of measuring ranges and process connectors according to customer’s requirement.

Screw antenna on the antenna connector. User can adjust the direction of the antenna to obtain a better signal strength.
Unplug the connector between pressure measuring part and the transmitting part if necessary.
Mount the pressure measuring part on process pipeline or tank or any other object. The process port should be screwed tightly to make sure that no leakage will occur.
The transmitting part can be mounted on walls or in equipment cabinet. When it is put in equipment cabinet, make sure that the cabinet is not signal shielded.
Connect the transmitting part with the pressure measuring part.
Press the button on the transmitting part to power on the device. The device performs self-test after power on. If the test passes, the red led on the button will blink in 5HZ for 3 seconds. If the test fails, the red led on the button will be lighted on for 3 seconds. The led will be lighted on for 10ms every 20 seconds when the device works.
The battery should be replaced by planed regular maintenance. Following the procedure to replace the battery in the transmitting part.
The device will send data to LoRaWAN® gateway. A gateway is usually associated with several network servers. If user works with particular network server, make sure that the gateway is compatible with the particular network server.
For example, if user wants to work with TTN network server, then user should choose gateway that is compatible with TTN, such as TTIG gateway and etc.
OTAA and ABP are both supported by PT701 User can configure access network mode and other network parameters via TTY serial port. It suggests that the mode and other parameters are configured in factory and users provide the necessary information when placing an order.
The DevEUI is printed on the label of the device.
ATech provides full support for connecting ATech sensors with AWS IOT platform. User can contact ATech for technical support.
User can configure the network accessing parameters and other parameters with TTY serial port on board. Unscrew the screws on the housing of the transmitting part and take off the cover. “TTY” port is 4-pin 2.54mm pitch pins with “TTY” characters printed beside it.
TTY is an UART serial port with 3.0V logic. The pin definition is as following.
VCC: On board Power for MCU, 3.0V typically.
GND: Common ground
Refer to the AT-command manual of the device on how to configure the device.
