We have tried connecting JSN-SR04T circuit with Arduino instead of STM8S003F3P6. We obtained Vpp as 92V but we are not getting maximum distance.

Ultrasonic sensor JSN-SR04T
We are facing some issues as well as we have some queries related to Ultrasonic sensor Module Integration with ESP32.
In JSN-SR04T, STM8S003F3P6 controller is used and 8 pulses of 40 kHz signal is generated from the controller & given to transmitting part of the circuit. The transmitting side Vpp voltage is nearly 96V when we use STM8S003F3P6. The maximum distance is 600 Cm.
We are trying to interface with ESP32 controller. We generated 8 pulses of 40Khz from ESP32 and we are getting 70V as Vpp. The only change is STM8S003F3P6 from JSN-SR04T is replaced by ESP32. We are getting 213 Cm as a maximum distance.
Please give me a suggestion on how to increase the sensor distance?
